Comment	> When a user has no folder in his account on our IMAP server (cyrus > 2.2), the menu in the left frame does not show up; in fact, the > request in this frame is crashing. > > Digging down the code, I found out the cause is how IMP treat the > answer to the NAMESPACE imap command. When the user has at least on > folder, the NAMESPACE command return the following: > > NAMESPACE (("" "/")) NIL (("[Shared]/" "/")) > > But when there is no folder (other than INBOX), the NAMESPACE command return: > > NAMESPACE NIL NIL (("[Shared]/" "/")) > > The way this is treated in IMP cause an entry "imp" to be inserted as > a child in the "imp" section of the menu tree, and later cause an > infinite loop when walking the menu tree, and PHP crash due to memory > exhaustion. > > I temporarily patched the horde/imp/lib/IMAP/Client.php file at line > 603 to replace > 'NAMESPACE NIL ' > by > 'NAMESPACE (("" "/")) ' > when found in the result of the NAMESPACE command, but IMP should be > able to manage the returned value > > NAMESPACE NIL NIL (("[Shared]/" "/")) > > correctly (as it IS a valid answer!) > > I tried to make a better fix, but the code that builds the menu tree > is a bit too complex for me...
