void Oxygen::ComboBoxData::setButton(GtkWidget*): Assertion `!_button._widget' failed.

问题: ubuntu 14.10 打开eclipse marketplace 闪退

解决:

Eclipse Luna crashes on new project in Ubuntu

This seems to be a bug in GTK according to https://bugs.launchpad.net/ubuntu/+source/gtk2-engines-oxygen/+bug/1242801 (there a similar problem for Meld was reported).

Another workaround mentioned there is for Oxygen, edit the normally already existing file/usr/share/themes/oxygen-gtk/gtk-2.0/gtkrc and change

`GtkComboBox::appears-as-list = 1`

into

`GtkComboBox::appears-as-list = 0`

This workaround is working for me.
