Where is my cursor?

[Joey Smith]

Sometime around 2.2, Pidgin stopped showing me the thin vertical bar
the represents my text-cursor - the position in the text that
currently has focus. This makes it incredibly hard to, for example,
correct a typo. It has never come back. Pidgin is the only GTK app I
see this behaviour in, and I've tried switching GTK themes to see if
it was a theme issue, to no avail. Anyone have an idea on how I can
get it back?
