Description Tex Morgan 2012-02-24 02:48:48 UTC

Application: umbrello (2.7.4)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed: I had added an attribute to a class but was having problems with my wireless keyboard so I tried deleting it manually using the mouse.  The item highlighted, then changed to wait for me to rename it, but I deleted it before I did.  Then the program crashed.

-- Backtrace:
Application: Umbrello UML Modeller (umbrello), signal: Segmentation fault

Comment 1 Oliver Kellogg 2012-02-26 17:03:47 UTC

Cannot reproduce using current trunk.
Based on your backtrace, looking at
tags/KDE/4.7.4/kdesdk/umbrello/umbrello/umllistview.cpp, line 1330 is:

    item->cancelRename(0); //double click can cause it to go into rename mode.

In the current trunk, this call is not done at all.
In fact, looking at `svn log umllistview.cpp` I see that a lot has changed in this area; see commits 1268936, 1268941, 1270599, 1270635, 1270636.
Please retry with current trunk or with 2.8.1 (will be part of the upcoming KDE 4.8.1)
