Comment 1 Milan Crha 2012-04-05 03:37:47 EDT
Thanks for a bug rpeort. I'm afraid this is related to lower libraries than to evolution. What is your version of gtk3, please? And when did you update to it (check with command like: cat /var/log/yum.log | grep gtk3 ). Does it help to downgrade to the previous version of gtk3, please? (yum downgrade gtk3).
Comment 2 Mark van Rossum 2012-04-12 05:27:27 EDT
I see this problem as well with

yum downgrade gtk3
returns "nothing to do"

I have not seen this in any other applications,
if it were a gtk3 bug it should occur with many applications, no?
Comment 3 Milan Crha 2012-04-12 05:35:24 EDT
I can reproduce this with gtk3-3.4.0-1.fc17, gtk3-3.3.20-1, gtk3-3.3.18-1, all are reproducing the issue. If I downgrade to gtk3-3.3.14-1, then this behaviour is fixed again, no unexpected selection is made.

Mathias, are you aware of any exact change in gtk3 which would cause such behaviour in gtkhtml3, please? Note that this does it only with iframes, which is basically gtkhtml3 in gtkhtml3 (if I click in the header part, which is the master gtkhtml3 widget, then there is no unexpected selection being done; while if I click in message body, the inner gtkhtml3 widget, then the selection happens - it seems like some event processing got dropped in gtk3 development).
Comment 4 Matthias Clasen 2012-04-12 06:08:50 EDT
The only thing I could think off here is 


But the details sound a little different here, so maybe this is something else after all.

Comment 6 Milan Crha 2012-04-13 05:39:07 EDT
hrm, adding the patch didn't fix evolution.
Comment 7 Milan Crha 2012-04-13 06:56:56 EDT
I briefly checked differences between gtk-3.3.14 and 3.3.18 and the main change seems to be the move to XInput 2.2 (and removal of --enable-xinput completely). The code change set itself, which contains many changes in copyright notice, makes a patch with 47418 lines, thus it's hard to find what caused this for someone like me, whom doesn't know gtk internals. I can attach it here, is it helps, but I'm afraid it'll not help much.

The main question: is it intended to keep backward compatibility on gtk3 side with the move to XInput 2.2? If there are things missing in gtkhtml3 to be done to work correctly with this XInput, then I'm fine to do it, I'm only not aware of any such notice, which I could easily overlook.
Comment 8 Rui Matos 2012-04-13 07:20:53 EDT
You can check if running evolution with the env var GDK_CORE_DEVICE_EVENTS=1 fixes the issue. If it does then it's something in the XI 2.2 code.
Comment 9 Mikhail 2012-04-13 08:50:00 EDT
Running "$ GDK_CORE_DEVICE_EVENTS=1 evolution" not solve this problem
