OpenCPN Crash on Mac OS

[diverdez]

Hello,
I'm looking for some help in tracking down a problem a friend has running OpenCPN on his Mac book. He's had many happy years of use out of OpenCPN and has recently been experimenting creating his own tile-based charts. He says that all was going well, until it wasn't. His 'last action' was to create a higher-resolution chart which he tried to import into OpenCPN and thus caused OpenCPN to promptly crash. It won't now start up again.

He's deleted the offending chart. He's deleted all charts. He's uninstalled OpenCPN. He's downloaded the latest dmg image. He's reinstalled. He's rebooted. But to no effect. OpenCPN still crashes immediately on startup.

He showed me this behaviour this morning, and I went through the same tidy-up, remove, re-install, re-run sequence. But, again, to no effect. The newly installed OpenCPN starts up, recognises that it crashed last time it was running and offers to start up in 'safe' mode. And then crashes again.

Now, the fact that I've uninstalled and removed everything I could find before re-installing and yet OpenCPN somehow still 'knows' that it had a problem last time it ran suggests to me that I've not done a good enough job of tidying up. I'd have assumed that a proper 'clean' installation would have no recollection of what had happened before, but I'm not a Mac expert.

The first part of the crash dump is shown below, highlighting that there was a segmentation fault in the main thread. But I don't know where to go from here. Does anyone have any ideas on how I can do a properly clean install, and then tell me where to go next to get OpenCPN running again?

Cheers

Rename the folder /<Your username>/Library/Preferences/opencpn to something else. OpenCPN should start normally as a completely clean installation (This is the only thing needed, all the reinstalllations, reboots etc. were not)
Do not delete it, all the routes, track, etc. are there and once you confirm the program stars fine, you will want to copy them back..

The backtrace is unfortunately almost useless, all it shows is that the crash happens when the chart canvas is being painted, we would probably need to see the chart that caused this whole trouble itself and the contents of the forementioned configuration folder.

That worked like a dream. I'm not sure why I couldn't find that in 'Finder', but using the terminal it took about 20 seconds. Should have tried that first! Thank you.

I would still much prefer to actually fix this, so if you can share the offending data, it would be appreciated.
