[Pkg-mc-devel] Bug#681539: mc: FISH freeze on large file copy from server (bt included)

Sat Jul 14 02:53:45 UTC 2012

Package: mc
Version: 3:4.8.3-3
Severity: normal

Dear Maintainer,

This bug occurs intermittantly but consistently when copying files --- usually files over a GB --- via
FISH.  If the copy is set in the background, the subprocess may be killed.  Otherwise, the whole program
freezes, as was the case when the backgrace below was taken...
