Package: chromium
Version: 20.0.1132.43~r143823-1
Followup-For: Bug #669338

For me the same symptoms seem to have started yesterday. It seems to be since
I updated on tuesday and restarted something yesterday. However I didn't
update complete system. I'll report if it manages to fix anything.

- The problem manifests even if I downgrade to version from testing
  (18.0.1025.151~r130497-1). It seems a bit weaker, but chromium still takes
  CPU time even if not being visible (and no plugins run).

- This system has Radeon graphics, so definitely not specific to Nvidia.

- I have plugins set to on click, so after restarting chromium, no plugins are
  running, but the problem does manifest itself. So not related to flash.

- I have closed all tabs one by one, made sure that
  /usr/lib/chromium/chromium is not open by any process using lsof and
  started chromium again. Even that eats significant amount of CPU. It does
  not manage to eat 100% though; it takes a few open tabs to do so.

- I started it from terminal, without --type=service, and checked the binary
  is not open before, so it does not seem to be specific to service either.

- top reports that processes eating CPU are the chromium processes and
  ksoftirqd, suggesting that the busy loop involves some system calls.

- When I start it from terminal, the output has:

QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.
unnamed app(6680) KMimeTypePrivate::ensureXmlDataLoaded: Missing <comment> field in "application/x-msdownload.xml" 
unnamed app(6680) KMimeTypePrivate::ensureXmlDataLoaded: Missing <comment> field in "application/x-wine-extension-api.xml" 
unnamed app(6680) KMimeTypePrivate::ensureXmlDataLoaded: Missing <comment> field in "application/x-wine-extension-secstore.xml" 
unnamed app(6680) KMimeTypePrivate::ensureXmlDataLoaded: Missing <comment> field in "text/x-component.xml" 

  for each initially open tab, but since the messages go away when I run
  /usr/lib/chromium/chromium directly without the --password-store=detect
  option but eating CPU does not, it does not seem to be related.
