[PD] Tcl/Tk error

[Christof Ressi]

hey oliver,

other users (including myself) have experienced this as well and it's a serious regression. Now that I have some time I want to investigate this. I've already fixed a related bug in September (https://github.com/pure-data/pure-data/pull/467).

can you do me a favour and file a bug report on GitHub? and can you try to find a minimal patch which triggers the problem (even if it doesn't happen all the time)? personally, I didn't have success in reproducing it, it only happenes very rarely and seemlingly randomly...
to all the other people who have experienced this: please help!

Christof
