Version:           1.0.1 (using KDE KDE 3.5.6)
Installed from:    Ubuntu Packages
Compiler:          gcc (GCC) 4.1.2 20060928 (prerelease) (Ubuntu 4.1.1-13ubuntu5)
 
OS:                Linux

Steps to reproduce:
1. Check that "Insert a remember line wen chat window is hidden" is checked.
2. Open Channel list for some network
3. Minimise Konversation's main window (check that ahctive tab is the channel list).

Looks like Konversation tries to insert remember line to channel list when the main window is hidden. Everything seems to works if that option isn't checked or channel list isn't active tab when minimising the main window.
