I think it's unrelated. (apart that you're both comparing version strings).

In your case it looks like WPKG clearly fails because it tries to parse another 
version digit which does not exist (dot at the end). This perhaps can be fixed 
in the code (I will have to check).

A work-around to fix it on all clients would be to just increment the revision 
of the package to something which increments on third digit (e.g. 6.0.341.4).

Thus WPKG would start comparing
6 <=> 6
0 <=> 0
341 <=> 340

And then stop since the new revision seems to be higher. So the questionable 
code which compares
4 <=> ''

would not even be executed. After successful upgrade then WPKG would insert the 
new package with updated revision (without trailing dot) into wpkg.xml and you 
can continue as usual.
