[Bug 1264315] [NEW] Interaction with onboard causes synaptic to become unresponsive

[Daniel]

Public bug reported:

Hi,

I'm filing this bug on onboard, but it might just as well be a bug in synaptic; I just don't know-.
- When onboard is running (it doesn't matter whether the onboard keyboard is being displayed/used), synaptic experiences major issues of unresponsiveness. Starting ssynaptic takes minutes, likewise  every time the quick search bar in synaptic is used.
During this time, the processes for synaptic, onboard and the accessibility dbus daemon consume lots of cpu time, (almost 100% of one core _each_). After a minute or two of waiting, synaptic becomes usable again, and the cpu load disappears.
- Onboards stay usable the entire time.
- Other applications do not seem to have the same issue.
- When onboard is not running, synaptic does not show this issue.

I've tried a quick strace, and it seems that synaptic spends the
unresponsive time sending lots of data using sendmsg(), but I haven't
figured out where to.
