Going to a presentation mode (tried with multiple pdf and epub files) and going out of it using ESC and then again going to the presentation mode (either ctrl+shift+p or from View toolbar) closes/crashes the file.
Works fine here, please post the output of running valgrind okular in a terminal and then trying to make it crash.
If you can provide the information requested in comment #1, please add it.
I am not able to reproduce the crash with when running as valgrind okular but i still have the issue when running as okular
Can you attach the valgrind log of when you do so anyway? It may contain interesting information still.
