[Pkg-ime-devel] Bug#704947: ibus-chewing-1.3.10 fails to save it's settings

[盧瑞元]

Package: ibus-chewing
Version: 1.3.10+clean-3
Severity: important

Dear Maintainer,

This issue/patch is coming from:

http://bugs.gentoo.org/407779

Copy and paste from the downstream bug report:

Problem and possible cause:
The internal configuration of app-i18n/ibus-chewing-1.3.10 are not saved
successfully.
This problem starts from app-i18n/ibus-1.4.0, where IBus changed their
configuration value type from GValue to GVariant.
ibus-chewing adapts the change by writing functions to convert between
GValue
and GVariant.  But it seems that the GValue->GVariant conversion function
dealt
with some types incorrectly, which caused g_value_get_uint() type checking
failure.


Steps to reproduce:
1. Install >=app-i18n/ibus-1.4.0.
2. Install =app-i18n/ibus-chewing-1.3.10.
3. Start IBus normally, switch to ibus-chewing input method.
4. On ibus-chewing language panel, click "configure" button (the second
button
from right).  Or if you have language panel embedded in menu, left-click on
the
IBus icon and choose the third item (Chinese: 設定).
5. Adjust the 5th setting (a spinbox with range 8-40, Chinese:
容納中文字數).
6. Click save (button at right-bottom corner, Chinese: 儲存).
7. Start another application, then repeat step 3 and 4.  You'll find that
the
setting has gone back to 8, not the value configured in step 5.

All three fields with a spinbox are affected.


Actual result:
The saved configuration does not persist and keeps going back to a certain
value.
Here's the output found when debugging with "ibus-daemon --verbose":
(ibus-engine-chewing:4097): GLib-GObject-CRITICAL **: g_value_get_uint:
assertion `G_VALUE_HOLDS_UINT (value)' failed
(ibus-engine-chewing:4097): GLib-GObject-CRITICAL **: g_value_get_uint:
assertion `G_VALUE_HOLDS_UINT (value)' failed
(ibus-engine-chewing:4097): GLib-GObject-CRITICAL **: g_value_get_uint:
assertion `G_VALUE_HOLDS_UINT (value)' failed


Expected result:
The saved configure should persist.
