[Uml-devel] Crash on start

[Vincent Ricard]

Hi,

I compiled umbrello from trunk/kdesdk and i had a problem; cmake did not finc 
FlexLexer.h (present in /usr/include on my box). So i removed 
HAVE_FLEXLEXER_H from the test around the add_subdirectory command. Next, the 
compilation and the installation were fine.

So, now, when i run umbrello i get :
ASSERT failure in QFont: "Must construct a QApplication before a QFont", file 
text/qfont.cpp, line 533

Here is the backtrace :

Previous frame inner to this frame (corrupt stack?)

Why the RubyCodeGeneration is used ? Is it normal ?
