mcedit crashes at startup

[ossi]

i have a script that wraps mcedit, which i have configured as the edit action for a certain file extension via mc.ext. somewhen recently, this stopped working - mcedit immediately crashes upon startup. i suppose this is related to the attempts to make it behave inside subshells.
