grep for just "leftMargin" as it is a layout property. It's gone in
later Qt 4 versions, and uic replaces it with the setContentsMargin
method. As Orion in this thread guessed, it looks much like qt4-devel
is not new enough and suffers from a uic code generation bug.

If you like to try a work-around, load the offending *.ui forms into
RHEL5's designer4, save them, diff against the pristine vym-1.10.0
to create a patch, and then build the patched vym.
