Package: xxdiff
Version: 1:3.1-3
Severity: important

xxdiff got uninstalled today for me because I decided to go ahead with
the QT upgrade due to the C++ ABI change.  So I built it locally from
the source package (againist current libqt3-mt libs).  Building it
worked fine, however the resulting binary segfaults:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread -1215293760 (LWP 22670)]

Running under valgrind makes it show the "could not run the diff"
message window.  valgrind is quite unhappy however, not sure that the
message from below is really pointing to the core problem.

tmake isn't used anymore.  We use qmake.  Closing this bug as done.
