This bug report is completly useless as it is: 
- I can not reproduce it here (you don't explain what type of new project) 
- You don't tell your QT version 
- You don't tell your KDE version 
- The backtrace is useless! 
 
Please give some more info 

I also have the same problem. It seems to be related to OPENING, not creating a 
project (I crash even when opening an existing project). 
 
Here is the backtrace:

By the way, I am running KDE 3.1.3 (SuSE RPMs) with Qt 3.1.2 

This is a duplicate of bug 62698 (or vice versa), I believe.  The stack traces look awfully 
similar. 
 

Chris is right. I was actually the victim of bug 62698. But I am not sure they 
are duplicates. The trace I gave IS identical to 62698, but one can't be 
certain that Dusty Ashley who originally reported it would have had the same 
trace as me... 

Seems likely enough. :)  
 
Closing as dupe. 

*** This bug has been marked as a duplicate of 62698 ***

On the other hand, Chris must be right: 
 
I DO get a crash when creating a new project while having another project 
ALREADY open, whereas if I have no other project open, I can generate a new 
project just fine. The backtrace (follows) does seem to indicate that it is the 
same bug:

So, they probably are dupes after all...
