I suspect that there was a race in your program (which was started
before tk8.5 is upgraded and linked to libtk8.5.so version 8.5.10, but
initialized after tk8.5 was upgraded, so tk.tcl was sourced from
8.5.11). Could you show me your script, so I'd try to reproduce this
error.

I'm not sure if it's possible to fix such kind of bugs at all...

Cheers!
