Description vanyossi 2014-07-03 02:23:19 UTC 
The crash only happens if invocation is set to "Key Combination". It works as expected with Mouse button -> SHIFT - mouse.

Probably if the input chosen should greyout the actions not supported by the type. As I guess even if it didn't crash it wouldn't work.

This is the backtrace. I set the Key Combination to "SHIFT", It crashes even setting the keycombination to any other keyboard key.

Reproducible: Always
Comment 1 Christoph Feck 2014-07-03 11:03:46 UTC 
The backtrace seems incomplete (the thread that crashes is missing). If you can reproduce it, please try to create a better backtrace. For more information, please see http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports
Comment 2 vanyossi 2014-07-05 01:59:17 UTC 
Update: First time it really was a freeze, so forcing quit produced previous bt. With recent Dmitry changes now Line tool crashes as described.

Here is the new backtrace: (followed this doc http://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces and used this command : thread apply all bt )

I hope this time the error is caught, if not, here is the options I chosen for the canvas input for making it crash
Canvas input settings > Tool invocation > Key combination : A : Activate Line Tool

Correct activation must be done with.
Canvas input settings > Tool invocation > Mouse button : A + Mouse button : Activate Line Tool

Yes, such choice must be impossible. Confirm.

We should categorize the shortcuts which support that and which not.
