Hi! I have Fedora 10 x86_64 & merkaartor 0.13svn-v13450, when I try to open file Soblahov.mdc (in attachment) merkaartor segfaults. Logs from dmesg: merkaartor[3627]: segfault at 0 ip 0000000000427bb2 sp 00007fff6ec3f900 error 4 in merkaartor[400000+355000]. Another mdc files are OK.

If you want to load your file, just change in line 8909

  <CommandHistory index="534" >

by

  <CommandHistory index="500" >

Now, I'll look into why it happened...

Hold on, the 500 should be 533

Thank you - it's working, one more question: when I close it without any changes, the "Unsaved changes" dialog is shown - why?

Wait before uploading.

I found the bug and will commit asap.
There was no data loss, so after the patch, your original file will work fine.

For the "unsaved changes", it actually means "not uploaded changes"... I'll change that
