Fri, 10 Apr 2026 19:46:55 +0000 https://bugs.horde.org/ticket/9301 unable to view/download attachments if mail is signed (S/MIME) I use Horde 3.3.9 and imp 4.3.8. If I try to access an attachment of an signed mail, the horde_main frame is repaced by a white page. If the attachment would have a preview (e.g. .png) this is not shown. There are nor errors shown or logged. Horde 3.3.8 with imp 4.3.8 works fine Mon, 11 Oct 2010 11:05:27 +0000 https://bugs.horde.org/ticket/9301#t60365 Please follow the hints at http://wiki.horde.org/FAQ/Admin/Troubleshoot#wsod to generate and find a useful error message. Thu, 21 Oct 2010 11:35:47 +0000 https://bugs.horde.org/ticket/9301#t60536 Sorry for missing the following error in the main apache error log [Thu Oct 21 14:31:38 2010] [notice] child pid 25540 exit signal Segmentation fault (11) attaced is a s trace of a apache-prefork that exits with a segmantation fault I could reproduce this bug with apache2-2.2.10-2.23.22.1, php5-5.2.13-0.1.1 and an other system apache2-2.2.10-2.21.1, php5-5.2.12-0.1.1 Thu, 21 Oct 2010 12:46:45 +0000 https://bugs.horde.org/ticket/9301#t60546 An strace doesn't help much, beside showing that the last thing that happend before the segfault was closing the imaps connection to mailserv08.uni-tuebingen.de. If anything, then a gdb trace would help, but this is still some issue in PHP then, not in Horde. Thu, 21 Oct 2010 13:12:19 +0000 https://bugs.horde.org/ticket/9301#t60548 Even if this is a bug in php, somthing in horde has changed between 3.3.8 and 3.3.9 thas is triggering this.
