#5054: Stop a cancelled transfer crashes Pidgin
-------------------+--------------------------------------------------------
Reporter:  CapnJB  |       Owner:  lschiere     
    Type:  defect  |      Status:  new          
Priority:  minor   |   Component:  unclassified 
 Version:  2.4.0   |    Keywords:  file transfer
 Pending:  0       |

 I've been trying to send a file to someone connected to AIM, and AIM
 automatically is canceling the transfer. Pidgin is not detecting that the
 transfer was canceled. However, the bug being reported here is that when I
 click on "Stop" in the file transfers window while this stalled transfer
 is selected, Pidgin segfaults. I can reproduce it every time on this PC.
 I'm using Pidgin on Linux.

 Also, I got a backtrace, but it doesn't look too meaningful (lots of ??'s)
 so I'll try building Pidgin with debugging support and getting a better
 backtrace.
