mc-4.6.2_pre1 freezes when copying files via fish vfs subsystem.
Killilng its child ssh process helps, but only to unfreeze mc, it is still not possible to copy files.
This bug is always reproducible with mc-4.6.2_pre1, even if all patches for mc-4.6.2_pre1 are disabled. But this bug is not present in mc-4.6.1-r4, where everything is ok.
Try 4.7.0_pre1. Reopen if this is still a issue.
For a quite long while I use mc from git, it works fine.
I do not want to downgrade to 4.7.0_pre1 )).
Reopening for correct resolution.
Assuming this is fixed then, since 4.7.0_pre1 is from the git you mentioned.
