RViz crashes often on starting 'irb2400_blending.launch'

[gavanderhoorn]

Vague, I admit, but often when starting the whole system in demo mode using roslaunch godel_irb2400_support irb2400_blending.launch I end up with the following:

Haven't had time to look into it, but -11 (SEGFAULT) seems to point to a potential issue with one of the RViz panel plugins.

Is this a Qt5 vs Qt4 issue? We ran into the same problem when upgrading to kinetic.

[gavanderhoorn]

No. This is all on Indigo. I don't have Qt5 installed.

[gavanderhoorn]

Additionally: it does sometimes work. If this were a library incompatibility it should always crash.

[Jmeyer1292]

It's a known issue. The blending panels frequently crash at start up. No one has looked into it yet.

Try again until it works.

[gavanderhoorn]

Figured.

I've been running the rviz node with a gdb launch-prefix for a day now: as expected it hasn't happened yet / any more ..

Crashing issue not occurring on Automate Demo computer. Changed milestones.
