Description Anatoly 2009-07-03 22:01:20 UTC

Version:           2.2.4 (using KDE 4.2.4)
Compiler:          gcc/g++ (Gentoo 4.4.0 p1.1) 4.4.0 
OS:                Linux
Installed from:    Gentoo Packages

Umbrello crashes when I try to save changes after removing two use cases from “Use case view” (using “Delete” command in right-click menu) which does not present on the sole “Use case diagram” (because was removed from it before) and after I “Save” a file.

I get this backtrace:
Application: Umbrello UML Modeller (umbrello), signal SIGSEGV

Thread 1 (Thread 0xb5cc7710 (LWP 27436)):

#3  0xb796daa8 in ?? () from /usr/lib/libkdeui.so.5
#4  0x00000000 in ?? ()

Not rather informative though. I have no debug versions of qt and kdelibs (I have debug version of Umbrello only), so gdb does not provide good enough backtrace:
Program received signal SIGSEGV, Segmentation fault.

Expected behaviour: have these two use cases removed from “Use case view” and successfuly save file afterwards.

Comment 1 Dario Andres 2009-07-07 12:21:55 UTC

I wonder why even when you have debug symbols for umbrello the backtrace is mostly empty. Are they properly installed? (or may be the backtrace is qt+kdelibs only?)
Thanks

Comment 2 Anatoly 2009-07-07 19:58:19 UTC

They are properly installed (I've just checked it out) and backtrace (which just popped up in KDE when Umbrello crashed) might be of qt+kdelibs.

Comment 3 Anatoly 2009-07-10 23:17:42 UTC

After rebuilding some libs with debugging support and disabling stripping of umbrello's binary I have got more informative log:

Comment 4 Dario Andres 2009-07-15 01:05:22 UTC

The backtrace looks related to the one in bug 168273. Thanks

Comment 5 Ralf Habacker 2014-02-19 08:53:01 UTC

do not crash in release 4.11.5
