Package: imp4
Version: 4.0.3-1
Severity: important
Hello,
using IMP 4.0.2 and 4.0.3 (same symptoms).
If (and only if) I use the folder prefix during login ("INBOX", using Courier
IMAP server) then the sidebar with the folders is not shown in the browser. In
the apache logs, the apache process which provides this HTML frame is killed
with SIGSEGV. Using the PHP debugger "apd", I see an endless loop in the
functions

This whole function call tree from APD is 53 MB as a text file. I can bzip2 it
and send it if you want. :-)
The segfault happens in libc-client2002edebian, called from php4's imap.so,
which seems to provide the IMAP functions. (gdb output from apache core file)

When I watch the IMAP communication, I see that if (and only if) I
specify "INBOX" as a folder prefix I see IMP repeatedly listing INBOX:

IMHO, php4 is right in killing this script because it loops endlessly. This
might be connected to Horde Bug #1620 but I could not test this yet.
Please investigate - if you need the full log files, just tell me. If you want
me to insert debug commands in the IMP4 scripts, I'll happily help.
Thanks!
Jens
