[PD] undo crasher in 0.36-test9

[David Sabine]

Hello Adam,

This crashed PD on my Windows XP machine too.

I followed the 5 steps you outlined and "Consistency check failed:
glist_findrtext" crashed PD.

Having said that, this is the only time that I've ever performed those 5
actions in precisely that sequence!

Regards,
Dave S
