OpenCpn crashes on hitting a config button (last but one in menu); Draw plugin?

There is nothing to delete, if you still experience your problem in the exactly same way, you simply did not fix the locale issue for your primary account properly.

Then, if you have time, I would like to see the stack trace of the crash, you would need to do the following to create one:

Add the following line to /etc/apt/sources.list.d/opencpn-ubuntu-opencpn-jammy.list:

deb https://ppa.launchpadcontent.net/opencpn/opencpn/ubuntu/ jammy main/debug

Update the APT data and install the GNU debugger and OpenCPN debugging symbols:

sudo apt update
sudo apt install gdb opencpn-dbgsym

Start OpenCPN in the debugger from terminal

gdb -ex run opencpn

Cause the crash

Execute bt command in the debugger

A lot of text will be printed to the terminal, copy it and send to me

Execute q command to quit the debugger

-------------

could I use these commands on my Linux Mint 21.2 Victoria?


I also can crash OpenCpn 5.8.4 with Draw 1.8.28.2, but by hitting the "Draw" button.

The crash is reproducable with my ODnavobj.xml (which has no faults)
Draw works if I start with an empty new ODnavobj.xml

I tried the above commands and got the following

Thread 1 "opencpn" received signal SIGSEGV, Segmentation fault. 0x00007ffff6efbcd4 in wxListBase::Item(unsigned long) const () from /lib/x86_64-linux-gnu/libwx_baseu-3.2.so.0 (gdb)

Maybe this helps

Probably yes, it should be Jammy if I understand their release notes correctly.

No, this unfortunately does not help much, we would need to see the whole backtrace (= what led to the SEGFAULT and where exactly in our code we likely tried to access a non-existent item in some list, not just that it happened).

Is that one line really all you got after you used the bt command in gdb? If it is, I'm afraid the only way forward is trying to reproduce the problem using your ODnavobj.xml

no problem, I try to append the XML

so I will rename to .kmz

I can reproduce the crash using your data with the released OD package, but it is fixed in the current codebase, you just need to wait for Jon to release a new version...

[Klaus_S]

thanks, with DRAW from the beta catalog (1.8.44.0) it works fine.
