After repeating enable-disable rqt_robot_monitor many (more than several dozens of) times on rqt_pr2_dashboard, rqt_gui segfaults.

Happens on @ablasdel's machine, but does not on mine (kept clicking for 5+ minutes x 2 times).

My environment:
ros-groovy-pr2-power-drivers/precise uptodate 1.0.9-s1354565896~precise
rqt commit 9eb8faa

To @dirk-thomas, @ablasdel
I even commented out graveyard but no difference.

The one we were looking at was an illegal instruction but we did see a segfault as well during the testing that we could not pin down.

This was happening pretty frequently when pointed at PRK, which is currently having motor trouble.

I changed the title of the issue since I can't confirm with rqt_robot_monitor standalone.

I kept rqt_robot_monitor running all night with rqt 8b22c21 but didn't happen, whereas with rqt_p2_dashboard it occurs often.

@ablasdel will look into rqt_robot_dashboard that's also used from rqt_p2_dashboard.

My particular crash only appears to be happening with pyside bindings; it hasn't happened yet with pyqt.

That is interesting. It looks like it must be robot monitor related because
it is the only one with a qtreewidget.

Could you please use both the pr2dashboard and in another instance have
just rqtrobot monitor? Just to see if you can reproduce it without the
dashboard. If you can we are barking up the wrong tree with our current fix
plan.

Closing this for now, since I've been testing this for awhile by running 2 rqt_gui instances (1 runs rqt_robot_monitor and the other runs rqt_pr2_dashboard) and no error occurred last 10+ hours.

Tested with
rqt 04f44e8
groovy-qt-gui-core amd64 0.2.8-0precise-20121208-2339-+0000
