Sometimes deleting it does not remove the node. Retrying to delete makes gIR crash. This happened to paragraph, line and text nodes.
The following trace is from deleting a text node for the first time.

Do you notice any particular sequence of steps which leads to the node not being removed? I'm unable to reproduce here...

@SantosSi

I could not identify any reproducible process leading into a crash regarding the not removed nodes.
But the one for the submitted trace is reproducible after a crash by re-opening the document and right-clicking onto the same node.

@manisandro

Can you share that document and specify which node to right-click?

How can I send you per PM?

Thanks for the document and steps. This is caused by an issue with the spelling library which stumbles over the apostrophe:

(gimagereader-gtk:737): CRITICAL **: enchant_is_title_case: assertion 'word && *word' failed

I'll investigate.

The crashes in the spelling library are simply due to empty strings passed to the library result in an assertion failure. This is addressed in beb11a6.

For the failure to remove the node, I still haven't managed to reproduce this, so any additional info for that would be welcome.

@SantosSi Please try with the latest master with the Qt interface (see compile HOWTO).
