Regression - software center some texts messed up (RTL)

[דוביקס]

This is likely a regression of Bug #733087 fixed in Natty.

Here are a couple of screenshots from the software center, Hebrew (RTL) environment:

As you can see, some texts are not properly right aligned - they seem to be a little shifted to the left. When this happens on lines that display the stars (ratings), the texts overlap.

Interessting, when I run "software-center --force-rtl" with a ltr locale the output looks ok. Running with
LANGUAGE=he software-center seems to be ok as well.

But if I generate a "he" language cache with
$ sudo LANGUAGE=he update-software-center
and then run
$ LANGUAGE=he software-center

I can indeed reproduce the bug for some apps (like vlc).

I suspect that something in pango tells us the wrong extents. Is there anything special in the chars for the lines that are wrong? (sorry, I'm totally ignorant about Hebrew).

Seems to me like the placement of the stars is prefect -
for example, if you look at the highlighted selection in the above screenshot you will see that there's a big space from the right to the beginning of the label. If you would align the string to the right then is looks like there's enough room and the stars would not overlap the label.

One more thing I noticed which might be very helpful:
Each cell of a program summary has two lines - The First is the program name and the second is a short description (in smaller font). If the description line (2nd line) is longer than the name line (1st line) then this bug occurs (otherwise it doesn't - the stars don't overlap text).
Note that when it happens, the 1st line is aligned to the end of the 2nd line.
That's probably the cause of this bug - the 1st and 2nd lines are somehow connected and both are aligned to the left of the longest label. Or, maybe you implemented this by using a single multi-line label and for some reason the text is aligned to the left in this single label.

in other cases where the 1st line is the longer one you can see the stars don't overlap the program name but note that the 2nd line is aligned to the end of the 1st line which is also looks kind of buggy for RTL users. You can see example for that in the above screenshot in the 3rd program with the "mms,wavpack, quicktine..." name.

I hope the above observation I made is clear enough. I'm pretty sure it's what caused this bug.

That version is no more maintained

Sorry that nobody could resolve this bug report before Ubuntu 11.10 expired. There have been many changes to Ubuntu Software Center since then, so the bug may have been fixed. If you still experience it in a current version (14.04 or 15.04), please reopen the report.
