#14215: gnttree falls into an assertion loop on tab key in New IM dialog
---------------------------------+------------------------------------------
 Reporter:  elb                  |     Owner:  sadrul
     Type:  defect               |    Status:  new   
Component:  finch (gnt/ncurses)  |   Version:  2.7.11
 Keywords:                       |  
---------------------------------+------------------------------------------
 This bug was triggered via the following process:

  1. Ctrl+O on the buddy list to open the menu, select New IM
  2. Select a 'Name' of a buddy which is in the buddy list for an account
 which is ''not'' the default account in the 'Account' field
     (The account field will change to an account which has this buddy in
 its list)
  3. Press <Tab>
  4. Press <Tab> again to drop to the OK button

 At either step 3. or step 4. (not sure which), finch went into a 100% CPU-
 consuming assertion loop with the following backtrace:

 The full backtrace is enormous, so I've elided it.  I have saved a copy if
 anyone is interested.
