Description Ilkka Tuohela 2002-10-29 09:02:55 UTC 
Sending multiple escaped %s string to gnome-terminal crashes it if tabs are
used: seems that the bug is in terminal's tab title handling.

Sending string %s%s%s%s%s to gnome-terminal's titlebar (with echo, using
escape sequences) shows in normal titlebar without tabs the text incorrectly
as -[27m-[27m-[27m-[27m-[27m. If current terminal window doesn't have any 
tabs it doesn't crash.

Same string crashes the terminal (and because of terminal factory, all 
terminals...) instantly, if current terminal has any tabs. Five %s strings 
is shortest one I could use to crash it, but for example %s%s%s%sfoo does
same thing: you need just a long enough string.

This problem was found when using gnome 2.1.0 developer packages, but I'm
quite sure it applies to 2.0.x versions as well.

Could you possibly get a stack trace using bug-buddy or gdb and paste
it into the bug to help us debug?
Comment 2 Heath Harrelson 2002-11-06 14:36:28 UTC 
User mistakenly put trace in another bug.  Here it is:

This appears to be a duplicate of bug 97199 / bug 95786, but this
trace is better, since it shows the text that's causing the crash.

Thanks again, Hile!
