This leads to a crash in the IGT module, so setting this to a higher importance.

User franza has pushed new remote branch:


also occurs with VS2012, setting this bug to critical

branch bug-18316-CrashPointListWidget fixes the crash but is more a workaround. However, I'm not sure if we can fix a bug in the RTTI. This branch should be merged for the release to fix the crashes in MITK.

[549354]: Merge branch 'bug-18316-CrashPointListWidget'

Now catching the exception and giving an error message if the error occurs. This avoids crashes.
