@Gautier_Avril: Apologies for not replying sooner. Regarding the script, this is what I meant:
from PySide.QtGui import QApplication, QIcon, QSystemTrayIcon
import sys, signal
app = QApplication(sys.argv)
QIcon.setThemeName('hicolor')
icon = QIcon.fromTheme('insync-normal')
tray = QSystemTrayIcon(icon)
tray.show()
signal.signal(signal.SIGINT, signal.SIG_DFL)
for path in QIcon.themeSearchPaths():
print "%s/%s" % (path, QIcon.themeName())
sys.exit(app.exec_())
Please copy it to a file like /tmp/script.py
then run it with /usr/lib/insync/py /tmp/script.py
then paste the output here. You can then stop it with ctrl+c
.
Additionally please try the test build for Ubuntu 17.04 available here: New Insync version: 1.3.15.
