[Uml-devel] Crash when exporting as picture

[Stewart Evans]

Hi,

I am using Umbrello 1.2.1 (built from source) with KDE 3.1 on Red Hat 
Enterprise Linux 3.
I get crashes very frequently when exporting pictures.  It doesn't seem to
be related to the specific diagram being exported or the export format.

 From this backtrace, I suspect it's a KDE bug or a version incompatibility:

Unfortunately I can't bugreport this against KDE because they're no 
longer accepting
bugreports for pre-3.2 versions.  And RedHat is in no hurry to release 
any KDE 3.2
packages. So perhaps this can just be considered an FYI in case others 
experience
similar problems.

umbrello -v output:
Qt: 3.2.3
KDE: 3.1.3-6.4 Red Hat
Umbrello UML Modeller: 1.2.1
