Description Luis Javier Merino 2004-04-13 19:20:55 UTC

Version:           1.3 (using KDE 3.2.0,  (3.0))
Compiler:          gcc version 2.95.4 20011002 (Debian prerelease)
OS:          Linux (i686) release 2.4.22

Hi all,

Environment:
	konsole 1.3 from kde 3.2.0
	Debian Woody
	glibc, libstdc++, binutils upgraded to testing
	kde from deb http://download.kde.org/stable/3.2.1/Debian stable main
	konsole is 3.2.0-0woody1
	LANG, LANGUAGE, LC_ALL = es_ES@euro

When i do man ksymoops, I get a crash when I get to line 338 of that man page, meaning I can see up to line 337, then konsole crashes.

Running konsole in valgrind, there are some invalid reads, the important ones seem to be
