Description Edward OCallaghan 2008-11-16 11:16:27 UTC

Version:           2.1 (using 4.1.3 (KDE 4.1.3), compiled sources)
Compiler:          cc
OS:                SunOS (i86pc) release 5.11

If you have a line typed, say:
$ gunzip -cd foo | tar -xf -
and you press, ^C, the shell should drop to a new line and cancel the last line typed. Like so;
$ 
Instead the session freezes so you can no longer type anything. Thus, you have to create a new tab to continue.

Thanks for your time,
Edward O'Callaghan.

Patch 16 (kdelibs-kpty.diff) was dropped from KDE 4.1.0 to 4.1.3, which re-introduces the bug. It's not actually in Konsole. Merged into trunk, anyway, and keep watching the packages in the 4.1 series for this regression.

SVN commit 884926 by adridg:

Fix 95% of bug #175283; there are still sequences that will wedge a pty, but I have not been able to reliably reproduce them.

Backport not necessary, we'll keep it in with the Solaris patches for now.
