Details

I was drawing on a drawing done in qcad2 - and now working on it in qcad3 - where I had saved it in the new dxf 2010 format (if this has any relevance) and then the computer ran out of power (old battery - I missed that I hadn’t turned on external power) - and shut down hard.

When I rebooted and tried to start qcad - it crashed on startup - giving only this output:
Debug: TIMER: 42 ms - “loading plugins”
Debug: TIMER: 459 ms - “initializing plugins”
./qcad/qcad: line 38: 2955 Segmentation fault (core dumped) LD_LIBRARY_PATH=”$DIR” “$binary” $OPT1 $OPT2 “$@”

I then tried removing the entire qcad-3.0.0-prof-linux-alt-x86 folder - and unpackaging the install tar.gz again.

It then started up and came to initializing plugins - 79% - and just hung - I’ve attached screenshot.

After I ctrl+c’ed it - it segfaulted and now it won’t even show the startup splash again.

I’m guessing qcad has saved some state somewhere.. but qcad hasn’t made a ~klavs/.qcad - so I don’t know where it is.

I would very much like to be able to use qcad again :(

I just found - that if I try to start qcad 3 or 4 times in a row - it suddenly starts.

If I then quit and try to start again - it still crashes a couple of times - before it starts. pretty odd.

You might be simply using the wrong QCAD package.

Note that after a (manual or automatic) system update you might have to install another QCAD package for Linux. You are currently using the package qcad-3.0.0-prof-linux-alt-x86, please try qcad-3.0.0-prof-linux-x86 instead. You can keep them both installed at the same time for testing.

SOLVED: It seems that was the issue. There's no complaints with the new version about corrupted glibc link list or anything either.
