mc-4.1.35 only shows the INFO subdirectory and the install and update scripts when pressing enter on a RPM file. No archived files can be accessed directly as in version 4.1.33. Another problem is, that it's not anymore possible to create a new empty file with shift-F4 as former.

This is not a problem of mc, than it's depending on the new version of the rpm package 2.5.5 (2.5.0 works). Couldn't track it down more exactly, but it's definetly not the rpm2cpio executable.
