Errors with none utf-8 strings

[Oliver Sauder]

Hi,

I use Natty on eee pc with Unity-2d. After about week of good work diodon doesn´t start and doesn´t appear on panel. Submenu on unity launchbar is empty. I can run diodon as superuser and it works well (but menu of sidebar of unity-2d still empty).
When the app starts in terminal I see this:

This is not normal. Therefore I have opened up this bug report.

For better investigation please attach your diodon history located in ~/.local/share/diodon/storage.xml

[Pavel (fpavel-is)]

I send the file.
Thanks for quick answer,
Pavel

Hmm, I can reproduce the issue GLib-CRITICAL **: g_variant_new_string: assertion `g_utf8_validate (string, -1, NULL)' failed. However this does not cause Diodon to crash on my system.

What happens when you delete the storage.xml before you start diodon?

[Pavel (fpavel-is)]

It works very well!
Thank you a lot.
Pavel

[Oliver Sauder (sao)]

All right. This means we have a problem with none utf-8 strings. Diodon handles such not correctly. This must be fixed.

[Oliver Sauder (sao)]

It turned out that building of the label of an item was error prone and led to invalid UTF-8 strings.

In your case this led than finally to a segmentation fault. This is now fixed in trunk which will be available in the diodon daily ppa soon (however the build farm seems to be used quite heavily so it won't be available before tomorrow)

Could you test this version with the old storage.xml file so we can really be sure that this bug does not occur again? Thanks.

[Oliver Sauder (sao)]

So finally the fix is now available in the daily ppa.

[Oliver Sauder (sao)]

Has been now released with version 0.5.0. If you still suffer from a similar issue please file another bug.
