Show Image Attachment broken? *solved* --> (mime_magic problem)

[Hellkeeper]

Hi,
got a Problem with Image Preview in Roundcube. (Version 1.0.2 and now with upgraded Version 1.1.0 the same)
When I want to open an attached Image (JPG/GIF/...) it will only show a broken Image. (Download of Image is OK!)

See Screenshot:


Any ideas? (No Errors within Roundcube Error Logs / Apache Error Logs)

Thank you

Did a little testing ...

With this URL it's not working (invoked by Roundcube on opening the attachment img):
http://www.server.at/?_task=mail&_framed=1&_action=get&_mbox=INBOX&_uid=9247&_part=2&_frame=1&_extwin=1

With this modified URL it's working?!?! (Setting _frame=0)
http://www.server.at/?_task=mail&_framed=1&_action=get&_mbox=INBOX&_uid=9247&_part=2&_frame=0&_extwin=1

Same for the embedded Image ...
Not working (original Roundcube URL): http://www.server.at/?__task=mail&_action=get&_mbox=INBOX&_uid=9247&_part=2&_embed=1&_mimeclass=image&_thumb=1
modified - working: http://www.server.at/?__task=mail&_action=get&_mbox=INBOX&_uid=9247&_part=2&_embed=0&_mimeclass=image&_thumb=0

alright - I guess I found the problem ... was about mime ...

NOT WORKING:      //$config['mime_magic'] = '/usr/share/magic';
WORKING:             $config['mime_magic'] = null;
