Crash on Startup on OSX 10.10.3 - Assertion Failed ripc_GetColor

[fiid]

I try to start Seafile client as downloaded from the site, and it crashes on startup. You can see it start to render the login window small in the center of the screen (presumably to animate it into the foreground), and then it crashes and exits.

I think this might be caused by a bug in an underlying library, some other projects seem to have the same problem. It also works on one of my Macs and fails on the other. :( Same crash with 4.1.6 and 4.2.0.

Looks like these issues may be the same, but in other projects.... neither of those guys seem to have resolved it yet either :(.

It seems the application loads a different version of Qt Frameworks from /usr/local/lib. Could you check whether there are Qt Frameworks installed at this path?

Or could you mail the full crash report to my email address rwindz0@gmail.com if you don't have much time. You can find the report in the Console application which is shipped by Apple.

I sent some crash traces to you directly.

I got the code to compile locally and started trying to figure out what was causing the problem. I messed with SeafileProxyStyle::drawControl to see if that was causing a problem, but that's very simple, and seems to not be causing the issue. I have been able to run it locally for a while, but it seems like this bug does catch up with it eventually. Moving a ui window between a retina display and a non-retina seems to cause immediate crash. Also seems like theres some retina issue with my locally compiled version because the button backgrounds look wrong.

I do have locally installed QT, but not sure that the package is referencing them. I did mess around with my qt installs to get it to compile though.

@fiid it looks like a non-trivial bug. Can you disable SeafileProxyStyle by commenting out the line app.setStyle(new SeafileProxyStyle()); in src/main.cpp to find if it matters?

BTW I double checked the shipped 4.2.0 release and found, saddly, it has a /usr/local/lib rpath prior to @executable/../Frameworks which should be removed in the next release.

I tried disabling SeafileProxyStyle in main.cpp and it doesn't seem to make a difference. It fell over when I hit the settings screen (I was trying to provoke it).

I think the release client may be working better since I've done a macport dance to de and re-install QT in order to get the compilation working. It was pretty unstable when I first tried, but now seems to be working better (!!??). Really not sure what's going on. I can mess with the compiled version more if there are suggestions as to what to change, but if it's not impacting a lot of people it might be a wild goose chase. More as the experiment progresses :)

Hi, I want to know how to create the DMG installation package of seafile-client on MAC
