Thank you so much for your reply, Duncan. I was unaware that I was using
html and not plain text, hopefully I have fixed the issue now.
As far as the bug is concerned, I had already renamed that file and
started the desktop back up, which worked. I have been experimenting
with customizations and I have narrowed the bug down to the icons being
placed on the panel. I know I had some bash scripts that ran wine games
on there, maybe that could have caused the issue. I will test this more
thoroughly and get back to you all, if this is indeed a kde issue and
not an issue with one of the packages.
Thanks again for your help,
