Unfortunately the backtrace is lacking debug symbols. If you are able to reproduce please install the debug packages provided by your distribution (please ask the distribution support channel on how to install them) and attach a new backtrace.
Ok I will upload the program with which it crashes so you can reproduce the bug.
http://www54.zippyshare.com/v/XEuO8bZs/file.html It needs Wine. wine --version: wine-2.0-rc3 (i think the latest)
Sorry, but I'm not going to download random windows applications to run them through wine.
Why? Anyway it happens also with Guvcview. I want to add that I am using nvidia driver.
