Version: (using KDE 4.2.1) Compiler: cc Installed from: Ubuntu Packages I opened a .png file for cropping on all four sides and I cropped the two sides that you can without rotating. When I try to rotate the image so I can cut off the top and left sides of the image, KolourPaint crashes. It Happens with Image-> Rotate..., Rotate Left, and rotate right. It also happens if I use the keyboard shortcuts to does the same thing. If I try to rotate the default image that comes up when KolourPaint is opened, the same thing happens. The KDE crash handler tells me: Unable to create a valid back trace. This back trace appears to be of no use. This is probably because your packages are built in a way which prevents creation of proper backtraces, or the stack frame was seriously corrupted in the crash.", it also says, '(no debugging symbols found)'. I am running Ubuntu Jaunty 64 bit with gnome desktop and some KDE apps. If there is any more info you need, please tell me and tell me how to get it.
What Qt version are you using ? You can try installing the "kdegraphics-dbg" package and reproducing the issue. You will get a better crash information (backtrace). Here using: Qt: 4.5.0 + qt-copy-patches-936035 KDE: 4.2.66 (KDE 4.2.66 (KDE 4.3 >= 20090310)) kdelibs svn rev. 939600 / kdebase svn rev. 939602 kdegraphics svn rev. 935854 on ArchLinux i686 - Kernel 2.6.28.7 I can't reproduce the crash Thanks for reporting.
(In reply to comment #1) > What Qt version are you using ? How do I find that out?
You can find out looking at the output of the shell command "dolphin --version". Thanks
