[Pkg-owncloud-maintainers] Bug#798509: owncloud-client: 100% CPU load all the time

[Alexander Dahl]

Package: owncloud-client
Version: 1.7.0~beta1+really1.6.4+dfsg-1
Severity: important
Tags: upstream

Dear Maintainer,

after upgrade from Wheezy to Jessie on my Samsung NC10 Netbook (Intel
Atom CPU, i386) owncloud-client uses the whole CPU all the time making
the whole system disturbingly slow. My owncloud server runs also on
Debian Jessie and the problem occurs in the local network with very
fast access to the server as well as abroad. owncloud folder has less
than 4 GB space used, so it's still quite small I guess. I do not have
this problem with x86-64 machines. This may be related to the
following upstream bug, which was also spotted in different Ubuntu
versions: https://github.com/owncloud/client/issues/2485 or maybe to
some other bug also reported for Ubuntu [1]. Debian testing already
has owncloud-client 2.0 depending on Qt5 so I did not try to use those
packages, there's nothing in backports, so I decided to file this bug
because I consider the package unusable on old/slow machines if it
eats up all the CPU.

I'm willing to support with tests or debugging, if somebody tells me
how.
