Description customercare 2018-07-04 10:00:55 UTC

Description of problem:

Today i played music with qmmp and noticed that i can't add song anymore from nemo. In the end i saw this message appearing:

qmmp: relocation error: /lib64/libQt5Gui.so.5: symbol _ZN15QVariantPrivate15regisperHandlerEiPKN8QVariant7HandlerE, version Qt_5 not defined in file libQt5Core.so.5 with link time reference

ALL QT5 Apps are no longer running.

Now the worst part them all : 

The last QT5 update is a week old ( see history of bug 1596926 ).

I guess an internal libcache got updated today, and now the missing dependencies are making themself noticeable.

I had to downgrade the entire qt5 framework to getrid of it.

Version-Release number of selected component (if applicable):

5.9.6-1

Comment 1 Rex Dieter 2018-07-08 14:18:35 UTC

In your case, there's a specific problem with one library:
/lib64/libQt5Gui.so.5
with missing symbols, so lets start there.

That said, I cannot reproduce this at the moment

ldd -r  /lib64/libQt5Gui.so.5
yields no missing symbols for me, but I'll try digging deeper later today.

Comment 2 customercare 2018-07-08 14:55:02 UTC

what I don't understand is, why it happenend several days after the update, in midair computing time, while qt programms were running. I did nothing special, a few mp3 (thats how I noticed it) , ff , thunderbird... thats more or less it.

A laptop, which installed the update on wednesday, a few days after we released the fix, did not have a problem on update day either. 

Is there a cronbased rebuild of some kind involved?

Comment 3 Rex Dieter 2018-07-08 15:00:56 UTC

None that I'm aware of (there was 'prelink' in the past, but I don't think that's used anymore)

Comment 4 Rex Dieter 2018-07-08 15:14:57 UTC

One debug step that may help, when problem occurs, please post output from :

ldd -r /usr/bin/qmmp

Comment 7 Rex Dieter 2018-07-08 15:27:37 UTC

OK, so it appears there are no missing symbols now and things are working properly?

Comment 8 customercare 2018-07-08 15:29:21 UTC

atm .. it's working as it should.

Comment 9 Rex Dieter 2018-07-08 15:30:57 UTC

OK, let's consider this resolved for now.  Please re-open if it happens again (and repost ldd output like you did above), thanks.
