Package: mutt
Version: 1.5.11+cvs20060403-1
Severity: normal
Tags: patch
Hi,
When IMAP header cache is enabled, mutt sometimes segfaults when trying
to open or close a mailbox. The segfault is repeatable and persists
until the mailbox changes (either by starting mutt with the header cache
disabled and deleting some messages, or by the delivery of a new message
into the affected mailbox).
I now did a debug build of mutt and got this:
Program received signal SIGSEGV, Segmentation fault.

The following patch makes the problem go away, but I'm not sure how
correct it is (it may just hide some other bug):
