Description Juergen Rose 2014-10-06 06:57:22 UTC
If I try to compare two files with meld, the meld window is opened and the first difference is shown. If I try to jump to the next difference, meld does not react. If I want to close meld by the file menu, it does not react. If I try a second time to close meld by the file menu. The file menu shows only a transparent frame. I can kill meld by clicking at the right upper corner x. Switching to fullscreen and back with F11 works.
Reemerging meld-3.12.0 did not help. It happens only on one system. Maybe a dbus problem? But I don't see any error message:

Comment 1 Pacho Ramos gentoo-dev 2014-10-06 09:36:26 UTC
Please provide two files here to let us try as it looks to work ok for me
Comment 2 Juergen Rose 2014-10-10 15:04:03 UTC
(In reply to Pacho Ramos from comment #1)
> Please provide two files here to let us try as it looks to work ok for me

I assume it is any dbus problem. After logging in from an other system the issue disappeared.
Comment 3 Juergen Rose 2014-11-05 12:47:34 UTC
It happens again with dev-util/meld-3.12.1. If I start meld I see the expected window with the first differences, but it seems almost not react on any mouse action. I can't scroll. If I click just after the start of meld to the File Menu it falls down, if I select "close", the differences windows is close, but meld is still open. If I click to "close" after an other mouse click inside meld, nothing happens. If I click to one left or right adjust files, the window is not changed. But it seems, that the adjustment took place. Therefore I will be ask to save the file, if I try to quit with CTL-Q meld afterwards.
Comment 4 Juergen Rose 2014-11-05 12:50:16 UTC
Maybe the issue is only connected with ssh sessions. The local call to meld just worked as expected.
Comment 5 Juergen Rose 2014-11-05 14:13:57 UTC
Investigating the issue further I found, that I have five systems, where meld via ssh works like charm, but I also have four systems, where it is not refreshed. I rebooted one of this four systems, After the reboot meld refreshes one or two seconds. I could scroll a little bit. Then it hangs again,
I checked dbus (systemctl status dbus) and dmesg, but I did not see any error.
Comment 6 Marius Brehler 2015-01-26 10:37:42 UTC
meld-3.12.0 is not in the tree anymore. The lowest version currently is 3.12.2. Does this problem still exist with the newer ebuilds?
Comment 7 Pacho Ramos gentoo-dev 2015-07-04 14:18:44 UTC
3.13.2 looks to work fine for me, please retry with that one
