FS#5825 - text_editor plugin segfaults on h1xx

the text_editor plugin segfaults, on the player as well as in the simulator. to reproduce the crash, take the following steps:
open the text_editor via the plugins menu and move the joystick into an arbitrary direction.

a backtrace of the simulator crash looks like that:

no details on what/who fixed this

That stack trace looks like it’s caused by the new list titles, but I can’t reproduce this issue. Either in the sim or on my H120. Any chance you could try this again with the latest CVS?

this trace is from the latest cvs. and i don’t think it has something to do with the list titles, because i also expierienced that crash some weeks ago.

Okay, the reason I say it was related to the titles is that strack trace goes right through the list title code. Odd. Maybe something in the text editor plugin is trashing memory. Someone else will have to look at this as I can’t reproduce it.

oops, my mistake, i just tried it again with a 20060814 version and at least in the sim it works fine. so the crash that happend a few weeks ago seems to have been caused by something else, which is fixed now.
