lsb-xpaint 2.7.0-1.lsb3 segfaults after getting a screenshot

Hello,

I have observed a segfault in lsb-xpaint 2.7.0-1.lsb3 (32-bit x86 executable) 
when running on an x86-64 machine. The OS used was SuSE Linux 10 Beta3.

The segfault occurs sometimes after taking a screenshot, saving it in JPEG 
format and then trying to create a new canvas or to take another screenshot 
(sometimes it occurs after multiple tries).

I have tried to compile the same version of xpaint from source, and it happens 
as well. With GDB, I have obtained this backtrace:

Program received signal SIGSEGV, Segmentation fault.

Please, does someone know what could cause this? I think it could be simply a 
bug in XPaint sources, but also it could be some kind of mismatch on the 
transition between 64-bit and 32-bit mode...
