Description

I have built Midght Commander from mc-4.8.4-2.fc18.src.rpm ( libssh2-1.4.2-2.fc18.src.rpm also needs to be installed, because this library in RHEL/CentOS is too old ).

Now when I try to edit any file in MC I get this error:

                                                                      
       ┌─────────────────────── Error ────────────────────────┐

Here's a backtrace:

This problem can be solved by installing aspell-en, but even when this package is missing/not installed, MC shouldn't crash/segfault.

  • Summary changed from mceditor/mc 4.8.4 crashes in RHEL/CentOS 6.3 to mceditor 4.8.4 segfaults in RHEL 6.3 when aspell (en) dictionary is not installed

libssh2-1.4.2-2.fc18.src.rpm also needs to be installed

This info is not related to this ticket.

MC 4.8.3 works just fine here.

This info is useless because 4.8.3 just doesn't have libaspell support.

This problem can be solved by installing aspell-en, but even when this package is missing/not installed, MC shouldn't crash/segfault.

mc doesn't know about installed dictionaries. mc get dictionaries list via libaspell.

I don't have installed aspell-en and my mc is not crashed. But I'm not RHEL/CentOS user.

Looks like RHEL/CentOS-specific bug. File a bugreport in RH bugzilla.
