smartpm sometimes calculates wrong transaction causing packages to be removed/upgraded wrongly

The following situation:
1) efw-locales-* requires the same version as efw-locales
2) endian-appliance requires efw-locales and every efw-locales-* package
3) there are updates for efw-locales, efw-locales-* and endian-appliance*

smart upgrade efw-locales

*should* update only all efw-locales packages, but in reality upgrades many more.

This happens with smart 1.4.1

I attach my debugging output and code which contain the debug prints.
The following should explain why this particular case happens, if you compare with the debug output it should become clear:

1) The package efw-locales is removed because can't coexist with the same but older package -> OK
2) Removing the efw-locales package requires removing all efw-locales-* packages which require efw-locales -> OK
3) Every efw-locales-* package is added to the updown queue, since we need this package really and need to do something later in order to fix -> OK
4) _pending() call: causes to upgrade all efw-locales-* packages, starts with efw-locales-ja -> OK
5) [001] _install(efw-locales-ja-2.10.14-0.endian6@i586) -> OK
6) installation calls _pending with nothing pending -> OK
7) back in recursion to _pending() call #4 (which installed efw-locales-ja)
8) does "Remove every requiring package, or upgrade/downgrade them to something which does not require this dependency", which removes appliance package -> NOT OK

I guess in _pending(), case PENDING_REMOVE, we have those 2 cases (description got from comments) where
1) "Try to install other providing packages."
2) "There's no alternatives. We must remove every requiring package."

Case #2 fixes the problem and has a "continue" at the end of the block, case #1 also fixes, but has no "continue", so the handling after case #2 takes place where packages will be "Then, remove every requiring package, or upgrade/downgrade them to something which does not require this dependency."d

I think case #1 lacks a "continue", since it is already fixed, we do not need to remove the requiring package.
