By default, Bugzilla does not search the list of RESOLVED bugs.
You can force it to do so by putting the upper-case word ALL in front of your search query, e.g.: ALL tdelibs
We recommend searching for bugs this way, as you may discover that your bug has already been resolved and fixed in a later release.

Description Darrell 2013-04-12 17:43:01 CDT 
As noted in bug report 1448, TDM currently does not correctly populate the sessions drop-down lists. On my system the only files populating the drop-down list are those files installed at /usr/share/xsessions.

Not yet knowing the root cause of the incorrect populating, TDM would crash repeatably every time I tried to manually change ~/.dmrc to "TDE" or "Trinity."

The crash handler does not provide a backtrace despite having debugging symbols installed.

To duplicate:

1. Edit ~/.dmrc to TDE or Trinity.
2. Start TDM.
3. Attempt to login but do not use the Default session.
Comment 1 Darrell 2013-04-19 15:01:43 CDT 
Updated test method:

1. Edit ~/.dmrc to TDE.
2. Temporarily rename $PREFIX/share/apps/tdm/sessions.
3. Restart X/TDM.
4. Verify the session drop-down list does not contain items from $PREFIX/share/apps/tdm/sessions. The list should be mostly limited to the items in /usr/share/xsessions.
5. Attempt to login but do not use the Default session.

Resolved in GIT hash 93bbac1.

Thanks for reporting!

No more crashing. Nice.

Always interesting to see the effects of missing brackets in code. :)

Thanks!

The missing brackets are mostly a legibility problem; I add them in because it is much easier to spot logic problems (such as this one) when they are present. :-)
