Whenever I click RMB on a blank space in a text frame i receive a crash (SIGSEGV).
Here is a traceback:

It's quite annoying, moreover, I get it only in one particular frame with particular contents. It looks similar to Bug #52051.
To make things funny - if I create another frame and RMB click, then nothing happens, but if I copy-paste contents of the first frame to the second one and RMB click. These "contents" are just a simple address.
