Has this profile been used in qTox too?

No. Never. Only uTox since the very old versions.
Confirmed on two PCs. And only with 0.11.1, old 0.9.7 was just fine.

Hm. After couple restarts on Win 8.1 this problem was gone.

That's really strange. We've had this reported before (and I could recreate it) on profiles created in qTox. Glad it started working again though. I'll see if I can find anything.

OK, thanks.
I'll check it with another uTox profile on Win 7 when I can get access to it.

Yeah, there's a race condition I know about if toxcore is able to start before the gui finishing it's init.

The same problem here. Windows 10 x64, uTox 0.9.7.
Have never used qTox or any other clients.

this should be fixed in develop via better tox core init from @cebe

Can still recreate on 65ab802

Still here in v.0.12.2

And in v.0.14.0 too.

does the copy button work?

I've been trying to reproduce this error for a couple of days, yet no luck here. I'll report, if (when) I finally catch it.

Got it!
Button doesn't work.

Still here in 0.15.0.

0.16.1
