Inline images issue (after Ubuntu 12 to 14 upgrade)

[DigiAngel]

Hey all.

So I have a DVR...fairly certain it's not RFC compliant when it sends snapshots.  That being said, Roundcube on Ubuntu 12 displayed these images inline just fine.  But this new version, 0.9.5 does not.  Here's a header:

I currently get a line with:

If I click download I can get the file, if I click show I see:

Code Select Expand

WARNING! This attachment is suspicious because its type doesn't match the type declared in the message. If you do not trust the sender, you shouldn't open it in the browser because it may contain malicious contents.

Expected: image/jpeg(.jpg); found: application/x-empty

Things I've tried changing...pointing to mime.types and mime.magic...installed ImageMagick and pointed to convert and identify...no luck so var:

Code Select Expand

$rcmail_config['mime_magic'] = 'null';

$rcmail_config['mime_types'] = null;

$rcmail_config['im_identify_path'] = 'null';

$rcmail_config['im_convert_path'] = 'null';


Is there something else I can do to troubleshoot this?  Thank you.

null is not the same as 'null'. Try mime_magic = null.

Thanks for checking here....in the config I have currently running, none of the null entries have single quotes:

After testing with the latest roundcube from source, I still experience this exact same behaviour...the current version with Ubuntu 14 is 0.9.5.  Thank you
