Comment 1 G Narvaja 2005-07-20 01:43:05 UTC 
Same results when using kcron 3.4.1 running in KDE 3.4.1 installed from binary packages in Debian.

Steps to reproduce:

1. Launch kcron
2. Expand "(System Crontab)" by clicking in the '+' sign.
3.a. Click in the PATH variable or
3.b. Click on the last task and go down with the arrow key

Thanks,
G
Comment 2 Kiril Simov 2005-08-28 11:46:01 UTC 
Analogous problem with RedHat FC4 - you cannot click on the variable because kcron crashes. Please, help!

Comment 5 Charles Thorpe 2005-11-17 00:13:13 UTC 
Confirmed with 3.4.92 (svn from 12/11/05). qt-copy from same date.
Gentoo Linux, gcc 3.4.4
