I hear a few canon staff browse the forum and it is a VERY busy one. Lay out all the symptoms etc of the problem and see what people say... you never know...
(It isn't especially good at the job, but I've easily have 5 Francs of entertainment out of it. )
I'm guessing this is fixable but I don't know if you have the tools and the nerve to fix this yourself. You can see the process on the following link and I guess the mechanism will be similar for the G9. If it happened to my G9 then I would attempt the fix myself but then I have taken cameras apart to mend them before. Mechanical cameras, that is. You have got to document everything and make diagrams of every step and even label the screws you remove so you know which screw has to go back where. This has to be done stone cold sober, of course, with good lighting and perhaps close focus spectacles.

You might get away with a simpler fix
Your stuck with this one if you want to keep your guarantee intact. It has to be Canon who fixes it and you will have to pay. Whether this is a camera fault or not is their decision and they will find in their own favour.
I would be tempted to pay Interdiscount their 80 CHF, get your camera back still broken, and try the simple measures listed at www.e18error.com which do not involve taking the camera apart. That way you should not invalidate your guarantee. If you find you can't get it working then send it off yourself to Canon to be repaired.
I suspect that a lot of these types of camera will develop this fault after a time.
Or grab the camera and not pay the 80 CHF
The camera was not suitable for the purpose for which it was intended...
ie taking pictures for an extended period of time .

Alsothe magazines K-Tipp and Saldo might be able to offer some advice...
Which branch of Interdiscount was it BTW?
If it is caused by dirt or moisture getting in, and given that interdiscount was able to say with almost 100% certainty that the camera would not be covered under warranty before Canon even looked at it, then this would indicate that this happens a hell of a lot, and that the camera more than likely has some kind of design fault. Therefore not fit for purpose.
It's far far more likely than you think - I come across computers everyday with fried logic boards, sound cards, video cards etc.
Do you really think that this kind of camera would be put to "professional" use by a pro when the pro already has DSLR's and lenses?
As for this particular problem being an electronic problem then I would disagree in that the lens stopping is a sign that the electronics are working and not the other way round. It has detected an abrupt resistance to the retraction or extension of the lens and stopped the motor to prevent possible damage.
I would say that Canon should keep statistics and if the lens fault occurs in the first three months of use more often than in the second or third three months of use then Canon should accept that it is a design fault and fix it under guarantee if the fault occurs in the first three months and make the effort to remedy the design fault for future models. But maybe that is too sensible for them and they would rather have their reputation for making retractable lens cameras permanently shot to pieces.
Karl nice gallery and good luck.
Interdiscount Shop 2 refused to exchange it, claiming it was the responsibility of Shop 1 to do so. Luckily I remembered the name of the guy in Shop 1 so he got a bollocking from the manager of Shop 2 and after standing my ground (and offering to charge them for my time to go back to Shop 1) I got the replacement from Shop 2.
Why do they make it so difficult to get a replacement (or perhaps even honour a guarantee) from a different branch?
Sorry, but their service really sucks.
