Hello,
I’m trying to track down a segfault when a canvas.draw() call is made in my GUI program using the Qt4Agg backend. I am running matplotlib 0.98.3 and Qt 4.3.2. I know the Qt version is a bit old, so I wanted to check if I should be suspicious of version incompatibility. I am working on a script to demonstrate the segfault.
Thanks,
Glenn
I'm using Qt 4.3.0/PyQt 4.2, compiled from source on RHEL4 with no problems, so it's not necessarily that your version is too old.
Once you have a script to reproduce and (ideally) a gdb backtrace, that should help us narrow down on the root cause.

The problem seems to be fixed after updating SIP from 4.7 from the ubuntu repositories to 4.7.7 from the source. I think it had to do with mixing threading.Thread with a Qt application, but I’m not entirely sure.
Thanks for the info anyway,
Glenn
