Thanks for the bug report.  I tracked the problem down to an attempt
to cancel a thread that was never created.  Because it couldn't find
any technology file, it never created a layout window, and likewise
didn't create the associated thread for capturing X11 events.  I have
already corrected the source distribution, and hopefully it will make
its way back into a new debian package.

It sounded like a mismatch between the install location given at the
time of installation vs. the install location compiled into the code
at compile time.  I can see this being an issue with pre-compiled
packages.  How did you solve the problem?
