0000691: OMNeT crashes on File Search

OMNeT crashes when doing a 'File Search'.

Reproduction:

1) Open the menu item Search -> Search, select 'File Search'
2) Enter some text in the 'Containig text' field, '*' as File name pattern, 'Workspace' as Scope
3) Click Search
4) --> crash

I have tried it with both JRE 6 and 7.
The OMNeT workspace is the default samples folder, plus INET 2.2 and my own project.

System specification:
Kubuntu 13.10 64bit
OMNeT++ 4.3.1
INET 2.2
No tags attached.

I have attached the command line ouput (Cmd_JRE*.txt) and error report (error_report_JRE*.log) for both JRE 6 and 7.

If they are needed, I can also upload the core dumps (but are have >600MB).

With JRE7, the search does not always crash, but sometimes works as expected.

Not sure we the OMNeT++ team can do much about this. The File Search functionality comes entirely from the Eclipse Platform. Can you reproduce the crash with a vanilla Eclipse installation?

We are upgrading to Eclipse 4.x as a base for subsequent OMNeT++ releases, perhaps that will solve the problem.

No, I can't reproduce it with vanilla Eclipse (I currently use Eclipse Kepler on the same machine, but have used in the past years also Helios, Indigo and Juno).

Are there any additional debug switches I can turn on to get more information on why the crash happens?

The error logs you attached shows that it crashes when SWT calls into GTK while deleting a combo widget or something like that.

C [libgobject-2.0.so.0+0x19528] g_object_get_qdata+0x18

What you can try is installing the Oracle (ex-Sun) JRE...

It is the same with Oracle's JRE (Version 7 Update 45):

I have also tried to install OMNeT on my Windows 7 installation (same machine), also with Oracle Java, and there it does not happen.

I have retested this with Eclipse Kepler (will be included with OMNeT++ 4.4) and cannot reproduce the issue.
