Created attachment 44124 [details] a new ebuild
Created attachment 44125 [details, diff] patch for libxklavier
I found the problem, the bug belongs to libxklavier... What do you think about "free" of static buffer ?? I post a quick fix (strdup the buffer). But I beleve that somebody have to rewrite the code in order to make this library thread safe and get rid of possible memory leaks (I can see them now).
added the patch to libxklavier-1.04-r1, please test
Patch fixes for me, Alexey?
Reopen if this is still a problem, thanks for applying foser.
