Description Andreas Veithen 2007-03-14 00:07:11 UTC
Version:           1.9.5 (using KDE KDE 3.5.5)
Installed from:    Debian testing/unstable Packages
OS:                Linux

KMail 1.9.5 crashes when attempting to create folder with slash in its name (e.g. "crash/me"). It first displays the following message:

Error while creating file crash/me: No such file or directory

And then:

Error opening [...]/.INBOX.directory/crash/me; this folder is missing.

After this, KMail crashes with signal 11.

A very similar problem has already been reported in bugs 120448 and 125044. However this still happens with a disconnected IMAP account on a Cyrus IMAP server. Looking at the resolution of bug 120448 and the code in newfolderdialog.cpp, I think this has to do with the fact that Cyrus uses "." as a folder delimiter: With my configuration, KMail disallows dots in folder names, but allows slashes. The error messages shown above suggest that KMail then crashes because the caching code for disconnected IMAP has problems with slashes in folder names. Either KMail should always disallow slashes for disconnected IMAP folders, or the caching code needs to be corrected to handle slashes in folder names.

Can you please paste the backtrace of the crash here?

Comment 3 Bram Schoenmakers 2007-03-14 22:36:49 UTC

*** This bug has been marked as a duplicate of 120448 ***
Comment 4 Bram Schoenmakers 2007-03-14 22:40:06 UTC
You're sure about version 3.5.5? Because since KDE 3.5.5, KMail refuses to add folders with /, it gives a message box.
Comment 5 Andreas Veithen 2007-03-14 23:31:47 UTC
I think this bug is not a duplicate of 120448. In bug 120448 the problem appeared with local maildir folders. This problem is indeed corrected in 3.5.5: for this type of account KMail refuses to add folders with a slash (I just checked this). However as explained in my initial post, the problem still exists with a disconnected IMAP account on a Cyrus IMAP server. In this case KMail refuses to add folders with a dot (because this is the folder delimiter on Cyrus), but doesn't check for slashes. But the presence of a slash causes KMail to crash.
Comment 6 Andreas Veithen 2007-03-21 21:15:29 UTC
The following patch should solve the problem. It makes sure that for disconnected IMAP accounts, slashes in folder names are forbidden.

Comment 7 Allen Winter 2007-03-21 21:49:44 UTC
thanks for the patch Andreas.

But it doesn't look right.
'/' is allowed in a IMAP account, however dIMAP creates a local maildir copy and there '/' are not allowed..

Comment 8 Andreas Veithen 2007-03-21 22:16:30 UTC
I agree with you, but the other solution would be to make sure that the code that handles the local maildir copy for a dIMAP account supports slashes in folder names. In your opinion, is the fact that this code doesn't support slashes a bug or is it a design issue, i.e. is it supposed to handle slashes?
Comment 9 Eugeniu Plamadeala 2007-06-01 04:28:32 UTC
Just tried:
* Creating a maildir folder with name "test1/test2" fails with a message saying 
"Folder names cannot contain the / (slash) character; please choose another folder name."
* Creating a maildir folder with name "test1.test2" produces a folder with this exact name.

Debian testing. KDE 3.5.5 and Kmail 1.9.5
Comment 10 Andreas Veithen 2007-06-07 10:09:55 UTC
@Eugeniu: As indicated above the problem arises if (and only if) using a disconnected IMAP account with an IMAP server that uses '.' as a folder delimiter (such as Cyrus). You didn't specify what type of account and server you use. Could you provide this info?
Comment 11 Raúl 2008-11-07 12:41:33 UTC
Still alive in kmail 1.10.1 on kde 4.1.2. See attached freshen backtrace:

When I try to create a dIMAP folder with / in its name, kmail refuses with a warning. So this is fixed, I think
