Comment 17 for bug 1376051

OK...I take it back...

The actual reason was that IDIOTIC and illogical naming.

I will never understand why a _fully published_ version of gparted in Utopic is called 0.19.0-1___build___1 and your still somewhat unofficial PPA-only version is called 0.19.0-1-___ubuntu___1.

Normally, the x.yy.z-p-ubuntuQ naming ought to be used for releases that are in the *standard* distribution, and not the PPA. It is always way better to indicate certain builds of packages coming from a PPA by using an appropriate filename (at least not the above one, that's for sure).
So JFTR, at the moment, 0.19.0-1build1 is the (non-working, crap) version shipped with Utopic, whilst 0.19.0-1ubuntu1 is the (working) PPA version. Just to get this clear for further readers running into this extremely time-consuming problem.

BTW sorry for the rude tone, but I've really wasted way too much pointless time with this stuff now, and that---may I quote the description---so-called "minor regression". I'd burst out laughing, if it wasn't so pathetic...? That oh-so "minor" regression will be enough for me for months again...

Mind you all of you, "essential tools with little bugs" and "essential tools that do not run at all" is not quite the same thing...
Lastly: YES 0.19.0-1ubuntu1 is the first version that works again since 0.18.x. Good Lord...don't get me started about the QA here therefore...
