+ Version: other
+ Platform: Mozilla 5.x
+ OS/Version: Linux
+ Status: NEW   
+ Resolution: 
+ Severity: normal
+ Priority: P2

+ Summary: IMP 3.1: "show unsubscribed" provokes many warning messages
+ 
+ In IMP clicking the "show unsubscribed" button under "Folders" provokes a stream
+ of error messages to appear (see examples below).  
+ 
+ We configured our UW IMAP server so that the IMAP root directory is also the
+ user's home directory (~), and we have the IMP config variable "show_dotfiles"
+ set to false (in conf.php), which is the default.  Hence doing "show
+ unsubscribed" will list a whole lot of files that aren't actually relevant as
+ candidate mail folders, and show_dotfiles = false does filter out irrelevant
+ files/directories with a "." prefix. Setting "show_dotfiles" to true produces
+ far fewer error messages, but does not eliminate them completely.
+ 
+ 
+ Our IMP host is running Red Hat Linux 7.3, Apache 1.3.23, PHP 4, IMP 3.1-2,
+ Horde 2.1-3 (all from RPMs).
