Description Onno Hommes 2009-03-28 15:54:09 UTC

Version:           2.2.1 (using 4.2.1 (KDE 4.2.1), 4.2.1-4.fc10 Fedora)
Compiler:          gcc
OS:                Linux (i686) release 2.6.27.7-134.fc10.i686

Maybe this is just a duplicate of Umbrello crashes after a few clicks because for me Umbrello is near unusable. I have not mastered to use this tool for a long time before it crashes. Any way here is 1 of the many reasons that crashes Umbrello:

1) Create anew sequence diagram
2) place to classes on that diagram which will result in showing their life lines (or swim lanes if you will)
3) Try to attempt to create a synchronous message between the two
4) Crash.

Now I have been able to create a synchronous message. It seems hit and miss with Umbrello. As I started this bug maybe it should just be marked duplicate of the bug that discusses Umbrello crashes after a few clicks. There is just no clear reason why things crash. Sometimes things work, many times things crash.

I decided to build a later version from march 25 2009 and still Umbrello crashes left and right. Here is a trace captured while working in a Sequence Diagram. I deleted one Combinded block alternative and after I selected a message in this view and see below:
