#2989: Pidgin crashes when logging in to MSN while typing other passwords too fast
-----------------------------------+----------------------------------------
 Reporter:  alvarezp               |       Type:  defect
   Status:  new                    |   Priority:  minor 
Component:  pidgin (gtk)           |    Version:  2.1.1 
 Keywords:  crash msn login 2.1.1  |    Pending:  0     
-----------------------------------+----------------------------------------
 1. Open Pidgin.
 2. Put MSN window in front of a Jabber window.
 3. Type your MSN password and press Enter.
 4. MSN password window should dismiss and the Jabber one should get focus.
 5. Type the Jabber password before Pidgin shows any MSN icons.
 6. Pidgin will crash.

 The bug is reproducable in this Sid box. I installed pidgin-dbg and got
 the backtrace. The first line corresponds to some moment right before step
 2. I censored my password from the line 'entry = 0x8672fb8 "2345678"' and
 noticed that line was holding my password without the first character.
