Comment 5 for bug 1360200

From the duplicate bug reports, it seems like calibre is crashing on a few linux and a few windows xp systems.

Windows XP: From the crash reports I've seen on windows XP, there doesn't seem to be very much I can do about it as it seems to come from Qt 5. Given that Windows XP is officially unsupported by Microsoft, I suggest you stay with calibre 1.48 on Windows XP if calibre 2.0 is crashing for you, until such time as you decide to update your windows.

Linux: It would help you run calibre in a terminal as

calibre-debug -g

and post the output. Also state what distro of linux you are running on.
