[Straw-devel] Straw 0.25 Was Quitting on Startup

[Dave Aiello]

After running Straw 0.25 for sometime, it suddenly developed a problem
where it abruptly quit shortly after starting up.  I'm running the
0.25.1-2.1.fc2.dag RPM on Fedora Core 2 kernel version 2.6.6-1.435.

Here's what happened when I run straw from the command line, rather than
the Gnome launcher:

I fixed it by deleting the files in ~/.straw except for the one called
"config" and restarting the application.

What causes errors like this?  Might it have crashed or might I have
killed the program while it was writing to one of the database-related
files?  Would it help if I provided that database-related files and the
log to someone for analysis?
