Good evening,

I am trying to help out w/ this bug, but don't understand it. Are you having problems with an USB Web Camera or just a Camera? Also what version of Kopete are you using? And what version of Kubuntu are using?

Thanks for updating this bug,

Jonathan

I don't know if this is related, but for some strange reason Kopete *insists* upon running my TV Tuner card for no apparent reason. This slows Kopete's startup to a crawl.

assinging it back to the kubuntu team as i am struggling w/ what t odo next

Hi, I'm Kopete's video maintainer.
This bug is the same as https://bugs.kde.org/show_bug.cgi?id=117537 . The problem that prevents me from fixing this bug properly is the fact some drivers, like Michel Xhaard's gspca1, behave wrongly, making not only Kopete but every program that uses usb webcams through gspca1 freeze.
Some drivers, like uvc, return an error (EINVAL) from a kernel call when the device is disconnected. gspca1 simply freezes.
There's no feasible workaround to address this bug, and the best way is to ask kindly Michel Xhaard to fix the bug in his driver, but it seems the man is not exactly helpful, as can be seen in http://lists.kde.org/?l=kopete-devel&m=119429215312848&w=2 .
Some people are trying to do a patch to Michel Xhaard's driver, but it would only help people if the patch can be included in the official gspca1 source code, or if somebody takes over gspca1's development and does the long due code cleaning and V4L2 porting.
My attachment is a program capable of testing a given kernel driver when a webcam is disconnected. Some changes must be done to the source code to make the program test your specific device.

About Kopete fiddling with the TV Tuner card, Kopete needs to scan the available devices to be aware of its properties. It's possible to a device to be opened by two programs at the same time (to get info about it) and that's what Kopete does.
I currently have three USB webcams (two gspca1 and one uvc), 1 DC-10+ M-JPEG capture card, one Pico2000 CCTV and one Hauppauge TV/FM tuner card, all connected at the same time for testing purposes. I use KdeTv constantly and it never conflicted with Kopete and vice versa (I tested it).
Maybe it's related to an specific device, and if some arrangement can be done to provide me one device of the same model for testing purposes, I'll gladly test it. Novell sent me a Logitech Quickcam Pro 5000 (thanks William Stephenson and Novell) and I made it work properly with Kopete in one afternoon. Please contact my nick at gmail dot com if you are interested.

P.S.: No, I don't make a living reselling hardware people send to me. :D I'm just unable to test against every device in the market, and some aren't even available in the local market and/or are too expensive (as The Quickcam Motion AF). So if it's not such a burden and you woke up in a good mood, donate a device and help a zillion people to use Linux and fix both this bug and Ubuntu's bug #1.

Should work in KDE 4.4.
