           Summary: Crash when opening LKML folder with IMAP
           Product: kmail2
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: cnu at cnu.no-ip.com


Application: kmail (1.13.7)
KDE Platform Version: 4.6.3 (4.6.3) (Compiled from sources)
Qt Version: 4.7.2
Operating System: Linux 2.6.38.4-ck3 x86_64
Distribution: "Gentoo Base System release 2.0.2"

-- Information about the crash:
- What I was doing when the application crashed:
Clicked LKML in the folder list. KMail complains about IMAP transport and then
dies. When I peeked with wireshark it looked like this:

8 LIST "" "INBOX.Mailing Lists.lkml"
* LIST (\HasNoChildren) "." "INBOX.Mailing Lists.lkml"
8 OK List completed.
9 NOOP
9 OK NOOP completed.
10 SELECT "INBOX.Mailing Lists.lkml"
* OK [CLOSED] Previous mailbox closed.
* FLAGS (\Answered \Flagged \Deleted \Seen \Draft)
* OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags
permitted.
* 94288 EXISTS
* 0 RECENT
* OK [UNSEEN 93016] First unseen.
* OK [UIDVALIDITY 1298023376] UIDs valid
* OK [UIDNEXT 94690] Predicted next UID
* OK [HIGHESTMODSEQ 65067] Highest
10 OK [READ-WRITE] Select completed.
11 UID FETCH 1:* (UID FLAGS)
* 1 FETCH (UID 1 FLAGS (\Seen))
* 2 FETCH (UID 2 FLAGS (\Seen))
* 3 FETCH (UID 3 FLAGS (\Seen))
* 4 FETCH (UID 4 FLAGS (\Seen))
* 5 FETCH (UID 5 FLAGS (\Seen))
* 6 FETCH (UID 6 FLAGS (\Seen))
* 7 FETCH (UID 7 FLAGS (\Seen))
* 8 FETCH (UID 8 FLAGS (\Seen))
* 9 FETCH (UID 9 FLAGS (\Seen))
...
* 59899 FETCH (UID 59928 FLAGS (\Seen))
* 59900 F

At some point Kmail starts sending RST stuff killing the connection.

The crash can be reproduced every time.
