Comment 44 for bug 515525

I just discovered that this bug is _always_ being triggered if I use GNOME Terminal 2.29.6 (2.29.6-0ubuntu5, why it's not 2.30 I have no idea) to run aptitude, yet on the same box if I run aptitude from xterm it works _unless_ I resize the xterm while aptitude is running, then I get this backtrace:

  I can confirm that KDE Konsole only fails when the window is resized. Xfce-terminal can fail, but it's very hard to make it fail, and it's about as hard in xterm. Whats interesting here is that GNOME terminal seems to be emitting spurious SIGWICH's as well as aptitude failing.
