Hi list,
When running the latest commit of the 0.10.2 branch, the control is not
returned in -pylab mode.
e.g.
* running ./ipython.py -pylab
* typing 'plot()'
* nothing happens
* typing 'show()'
* control is not returned, even when closing the window
This problem is because check_gtk sets interactive to false and returns
the tkthread backend. But when using -gthread (which is default here),
everything runs as expected.
The patch below fixes the problem for me, but do'nt know if it's a
proper fix.
(CC'ing the author of commit 3e84e9f446b752aef4c798b3a086084b5cdcb679,
which is the first bad commit)
