Segmentation fault

I can't open NaSC, through the terminal application it shows me the following output:
$ com.github.parnold-x.nasc

Segmentation fault
Thanks but not enough information to do anything.
I have the same issue. Installed 0.6.0 on Manjaro from AUR. It ran exactly once and after closing it it would not start any more with this

[1] 31657 segmentation fault (core dumped) strace com.github.parnold-x.nasc
basically i just removed the nasc.sheets
rm /home/philipp/.local/share/nasc/nasc.sheets
and it runs again.
@dadaphl Thanks. Ok it seems to be something in stored sheet. Strange.
Can someone post a nasc.sheets that leads to a crash so I can start from there.
Same problem here. Ran once after install and then segmentation fault. Also pasting contents of nasc.sheets

$ cat ~/.local/share/nasc/nasc.sheets

@rythmkraze Thanks. Pushed a fix.
Hello, I am having segmentation faults on regular occasions. The only way to work it out is to remove the nasc.sheets file.
For the seg fault to occur, one needs to run the program and click on the "Open Sheets" icon on the top left.
Here is the command line:
(19:42) $ com.github.parnold-x.nasc -d

Here is the content of nasc.sheets:
sheet1-§-5500 * 3 + 9600 + 7100\n\n9600 + 10%\n\n2^44 / 1000 / 86400 / 365\n\n52650 / 81\n\n15000 * 12 / 3.657\n\n8000 * 12 * 40\n\n\n300 * 7 * 0.03\n95 / 300\n\naccounts = 8000 + 22400|§§|sheet2-§-42|§§|sheet3-§-43
Thanks for the sheet. I think it's fixed now
Unfortunately, it still crashes for me more often than it doesn't with pretty much any sheet, e.g.:
sheet-§-dddd|§§|sheet-§-
Still is my instant favorite calc. Thank You!!
