I have reproduceable crashes of current remmina 1.2.0-rcgit.9, if i copy a file or image. Kubuntu 16.04.
GDB backtrace is available at http://pastebin.com/jceCGgkR
Fell free to post here if I can provide further information.
Are you using remmina on the PPA or did you compiled it by yourself ?
Fix a realloc of 0 bytes (==free) double free crash, issue #792
It happened to me also, 1 hour ago. Small fix pushed now.
Thanks for the quick fix, seems fine after I tried the new build right now. I'll keep testing over the workday :)
PS: I use the PPA
