Browse hangs when trying to open file:///home/...

[walter]

Running an up-to-date jhbuild on Ubuntu with Browse 103, I ran into this error trying to browse my home directory:

Ok, I see this as well on Soas - have to find out what the issue is here.

Seems to be caused by Mozilla initializing libgnome implicitly so it can use gnome-vfs to query for icons to display the files.

We can workaround this issue by initializing lbgnome ourselves in webactivity.py:

Workaround pushed in ​http://git.sugarlabs.org/projects/browse/repos/mainline/commits/c19e24eb

In jhconvert distros I wrapped this hack to try...except
I guess fetching python-gnome only for this workaround code is a bad idea

at least on gentoo with xulrunner-{1.9.0.8,1.9.1_beta3} Browse shows ​file:/// well w/o this hack

Sounds good, this hack is needed only in platforms where xulrunner is built with gnomevfs. I hope that Mozilla drops completely gnomevfs in their next release:

The upstream bug has been pushed but I'm not sure it will make 0.86.

[erikos]

Is this ticket still open, to track the upstream bug? Or to remove the code again we added as workaround?

Both things!

[RafaelOrtiz]

Update: the upstream bug has been fixed, but we cannot remove the workaround yet,
because it needs gvs/gio migration, that we don't have yet.

[manuq]

This is obsolete, the workaround was removed in the port to PyGI, commit dec602fda0890bdbfb121107b9bb39f7954a9cd5 . Closing.
