Bug#761822: gnome-online-accounts: Evolution Google-calendar support requires extra package

[Vinothan Darael Shankar]

Package: gnome-online-accounts
Version: 3.12.4-1
Severity: normal

Gnome-online-accounts appears, by default, to set up a Google account to have its calendar displayed in Evolution.  However, on a fresh install, when one tries to open a GOA Google calendar, Evolution times out.  This happens until the user installs the evolution-webcal package, but the need to do so is not noted anywhere.

Either GOA should hide the "enable calendar" option for Google accounts if evolution-webcal is not installed, or it should depend on - or at least Recommend - evolution-webcal.

This is presumably /also/ a bug in Evolution, in that Evolution shows the possibility of connecting to a Google Calendar when it doesn't have the required plugin to do so, and that its error message is inaccurate.

To summarise:

Expected outcome: freshly-configured google account on new install has calendar shown in Evolution

Actual outcome: calendar is listed but appears to time out rather than fetch events.

Steps to reproduce: remove evolution-webcal if installed (noting that this causes no dependency issues), configure a Google Account through GOA, observe that the GOA calendar in Evolution appears to time out.

Steps to work around: install evolution-webcal and notice that Google Calendars immediately work in Evolution.
