Summary0000422: Kdenlive will load bogus file as jpg
Description- type this in a terminal "echo foo > test.jpg"
 - add test.jpg to the list of clips: weird, huh? It does _not_ look healthy to me :-/
 
 There should be a mechanism to check the validity of clips before accepting them on the timeline. Perhaps there already is, but this information gets lost somewhere in the kdenlive <=> mlt++ <=> mlt <=> ffmpeg chain.
Additional Information*Sometimes* this will crash kdenlive, but mostly it will just load a "bogus" image, green/red/weird stuff.
TagsNo tags attached.

 OK, its just one of those days. Back to "assigned status", and thanks ddennedy for accepting it.

 OK, this now reliably crash kdenlive. I suspect that mlt now (as intended) returns a NULL producer whenever a clip can not be loaded, but that Kdenlive (unintentionally) does not check for this, rather just assumes the producer is != NULL.

Checked using these versions:
Kdenlive Builder Wizard version: 0.7.1

Attaching stacktrace shortly, changing issue to Kdenlive also.

 I can confirm that the usage of a null producer is the problem:

 @Madsys - Sorry. Changing from Assigned to Acknowledged was an accident rather than a misunderstanding. Thanks for reverting that.
