QTextCursor segmentation fault with Frescobaldi

[rvj]

When running Frescobaldi in text edit mode, swiping text with a mouse to select it, upon releasing the left mouse button, I get a segmentation fault. Lately I've seen the following error message:

$ frescobaldi Fragile_bits.ly
QTextCursor::setPosition: Position '28326' out of range
Segmentation fault frescobaldi Fragile_bits.ly

This wasn't happening a month or two ago. I'm trying to run gdb to pin this down further, but not sure on what I'm doing. I tried invoking

$ gdb --args frescobaldi Fragile_bits.ly

but it complains that

Starting program: Fragile_bits.ly
No executable file specified.

I need some guidance. Thanks!

$ gdb --args frescobaldi Fragile_bits.ly

This should be

Code: Select all

$ gdb --args Fragile_bits.ly frescobaldi

The info page seems to say that OP is correct:

Code: Select all

   You can optionally have 'gdb' pass any arguments after the executable
file to the inferior using '--args'.  This option stops option
processing.
     gdb --args gcc -O2 -c foo.c
   This will cause 'gdb' to debug 'gcc', and to set 'gcc''s command-line
arguments (*note Arguments::) to '-O2 -c foo.c'.

The program's name is given to the right of --args, and is then followed by the arguments for the program.

I can drop the Fragile_bits.ly from the calling argument and access it within Frescobaldi. Hence I have tried

gdb --args frescobaldi

However I get the complaint

"/usr/bin/frescobaldi": not in executable format: file format not recognized

This file is only 222 bits large:

$ ls -la /usr/bin/frescobaldi
-rwxr-xr-x 1 root root 222 Jan 17 09:13 /usr/bin/frescobaldi

That suggests that /usr/bin/frescobaldi is not an executable, but a script. Run the interpreter with frescobaldi as an argument. I see that the package accepts PYTHON_SINGLE_TARGET, so this is probably a Python script.
