Servererror (Not Found) when changing IMAP Folder

[kriztan]

I'm using Roundcube 0.4.1 with hmailserver 5.3.3-B1879 on a Windows Server 2008 system. When I change the IMAP folders I got a Servererror (Not Found), but the content of the folder is displayed. This error appears on IE and FF. In the log files is no error reported.
Any ideas?

Ditto! Updated yesterday to 0.4.1. When I'm collapsing/expanding subfolders I got the same error and the behavior as above. When reverting back to 0.4, I have no problem. I'm using Courier and as client Google Chrome.

[edit]
Checked my imap log, but can't see any error or unusual things. My guess it has nothing to do with imap.

sounds like a known bug, see #1487023 ((De)Collapsing folders displays "Server Error! (Not Found)" error) ? Roundcube Webmail

Patched, working with FF and IE.
Thanks!
