gdict-applet hangs on "algae"

[norjaidi]

A strange bug. Looking up "algae" hangs the applet, either
by entering the word, or clicking the word in the spellings sidebar.

Detail:
  Dist: Hoary
  server: dictd running on localhost
  dictionay: dict-gcide
  strategy: already tried "exact", "prefix", "lev", all hang

The command line dict runs fine with "algae".

Thanks for your bug. Have you planned to update to Ubuntu breezy (5.10), maybe
it's fixed with it. It works fine for me. Does it happen with the
gnome-dictionnary UI too or only the applet? Could you get a backtrace of the hang?

[norjaidi (jaidi)]

gnome-dictionary also hangs with "algae". As for Breezy, that has to
wait until the end of the teaching semester. (Or until I can find
a spare computer to victimize).

Anyway, even if it's fixed in Breezy, I believe it's worth looking
into this bug. May be it's not really fixed, but rather made dormant
by changes in the dictionary entry.

I have 4 sample backtraces below. It seems that the infinite loop
is within gdict_defbox_get_word ().

I have upgraded to breezy. The bug no longer appears
(but, as I commented earlier, it may simply be dormant).

[Daniel Holbach (dholbach)]

Thanks for following up on this bug. I close the bug for now. If the problems
should reoccur, please REOPEN it. Thanks.
