Description Paul Lutus 2015-10-16 08:27:13 UTC

I would love to have used your formal in-app bug reporting system, but the program offers to install additional bug reporting packages, then refuses to install them with the explanation that the bug reporting system doesn't have root authority to install packages, but without taking the self-evident step of asking for a root password.

Anyway, given the complete failure of your bug reporting system for a trivial reason, I can only say that, if one enters a value of zero for "tilt x", which by the way should be called "translate X" to agree with accepted graphics and mathematical terminology, the program crashes and exist.

Here's an application image capture just before the fatal change to "tilt x" of zero:

Reproducible: Always

Steps to Reproduce:
1. Run kdenlive
2. Set up an effect of "Crop, Scale and Position"
3. Set a "tilt x" of zero.

Actual Results:  
At step (3) above, the program crashes and exits.

Expected Results:  
The program doesn't crash, but if it does crash, the bug reporting system has the good sense to ask for a root password so it can install debugging packages and produce an actually useful bug report complete with stack trace.

See above.

Paul, I only see the "Crop, Scale and Tilt" effect, so I'm assuming this is now the same the one you refer to. (I seem to remember that it has been renamed.)

I've tried to reproduce, but the current stable 16.04.2 and beta both don't crash when setting the Tilt X effect parameter to 0. The image is moved offscreen as expected.

Can you please check with recent stable 16.04.2 or current beta if you can still trigger this crash? If not, I would like to ask you to be so kind as to close this bug report. Thank you very much for your cooperation!

Using today's git build and effect "crop, scale and tilt" doesn't crash as suggested. Could be marked as resolved.
