the backtrace is rather incomplete. Most likely the crash is already fixed in a more recent version. Try at least version 4.6.3
Comment 2 Thomas Lübking 2011-05-31 19:29:14 UTC 
There won't be a better "backtrace" - it's probably bug #241163

@carlo
a) do you have an nvidia GPU?
b) you'll have to upgrade to 4.6 to disable the lanczos filter or 4.6.3 where this should be fixed or add your GPU to the blacklist list for the Lanczos filter to prevent this - if it is #241163

since it is simply not possible to get a better backtrace for this w/o patching Qt, i'll assume and mark it a dupe - we couldn't say better anyway as long as it's not explicitly reproducable :-(
