OK, in that case probably some other issue. Can’t really say more from  
afar.

Cheers,

Hi,

yeah basically it’s not a big deal, just a bit anonying. However it can  
be  
probably problem with glib since my RHEL6 probably has some ancient  
version  
…

Thanks,  
Nemanja

I think we’ve seen this before with certain versions of glibc (possibly  
another library that we haven’t looked at). It used to effect older  
versions of Ubuntu (14.04 IIRC) but not the latest couple of versions.  
We  
tried to track it down, but since it looked like it was in glibc and was  
fixed with newer versions (and it only happens on exit), we didn’t go  
too  
far in looking into this one.
