Bug 112867 – gdm/X crashes with excess of characters displayed in Firefox

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Bruno Laturner Lemes 2005-11-17 18:08:03 UTC]

I'm helping a friend to build a wiki site at ajudalinux.org/wiki and I stumbled
in a small bug/misconfiguration of the MediaWiki/PHP/DataBase/whatever software
there: for every single quote( ' ) you put in an article and you send the page,
it will make two single quotes( '' ).
With two it will make four, four makes eight, and so on. After a few previews of
the text I had two huge one liners(it doesn't break the line because it doesn't
have spaces) composed of single quotes, one for the previewed text and another
for the edit box.
I kept hitting the preview button, two horizontal bars formed in the edit box
and in the actual page. After a while, maybe after 15+ previews(I didn't count),
the screen went back to tty1. The X Server had crashed(or gdm maybe), but then
it returned since I have xdm running as boot service. It was like pressing
Ctrl+Backspace, but w/o doing it.

I don't know if it was the excess of characters, or if the horizontal scroll bar
overflowed, or maybe the apache server didn't like to be poked like that :), but
that was quite like the digital version of a punch in the face.

/var/log/messages had this in it:
