Bug 141110

Version:            (using KDE KDE 3.5.6)
Installed from:    Compiled From Sources
Compiler:          gcc 4.0.4 
OS:                Linux

LOADED PLUGINS:

None that I am aware of.

HOW TO MAKE IT HAPPEN:

If you attempt to open /etc/hosts is says it cannot be done (but the file does exist).  
"Could not load file '/etc/hosts'"
If you try it a second time you crash.

BACKTRACE:

Using host libthread_db library "/lib/libthread_db.so.1".

EXPECTED BEHAVIOR:

I realize that /etc/hosts is in the wrong format
and should not be editable, but crashing seems
to be the wrong response.  I think after the first time you open a file in the wrong format the state of the application is not reset correctly.  I expect the application not to crash but instead say something like "/etc/hosts is not in the correct format for Kommander".
