Recently I've been using a little python program called Timeline on my Ubuntu 15.04 system.
Today, however, it stopped working and now gives me the following error when I try to launch if from the command line.
(timeline.py:10359): Gdk-CRITICAL **: _gdk_pixmap_new: assertion '(width != 0) && (height != 0)' failed
(timeline.py:10359): Gdk-CRITICAL **: IA__gdk_cairo_create: assertion 'GDK_IS_DRAWABLE (drawable)' failed
Segmentation fault (core dumped)
As Timeline relies on wx widgets (python-wxgtk2.8 on Ubuntu) and associated libraries to run I thought there might be a problem with the package though a purge and reinstall of these has not fixed the issue.
I redownloaded the source in case something in the local install had changed, still no joy.
A look through other recent updates show no other obvious candidates that could have caused the breakage.
I've also spun up a lubuntu 15.04 live session where Timeline ran without issue.
Any idea where to look next?
