Summary0016411: Scribus crashes when calling scribus.redrawAll() function
DescriptionScribus crash when call scribus.redrawAll() API function. I have multiple textframes, images, rects and lines in sla document which are created with python API functions. Crash appears in somehow randomly but It will eventually happen when rects/lines are drawn and scribus.redrawAll() called. I have self compiled 1.5.6 source code and I reproduced the error with Visual Studio 2019. I can see that there occurs some problem inside LineBox::drawBackGround function. Problem is that (const CharStyle& style = box->style(); ) style is a faulty object and does not contain CharStyle. GlyphBox seems to be otherwise ok.
Additional InformationDump file size was 575Mb and I could not attach it here.
TagsNo tags attached.

This is apparently a case where a dump will not be really useful as the root cause of the crash will not be in the stack. I suspect this LineBox::drawBackground() to be performed on a text layout which has been invalidated by some text modification. So to continue investigating, I will need any element which allows me to reproduce the crash: script, document, etc...

It would be far too complicated to deliver a working running environment. Here I attach two py files and one sla document, that are essential with this problem.
My software calls display_neo_drag() function that calls _doc_group_highlight_ex and _paint_group_clear_article_ex functions. Crash happens always inside _doc_group_highlight_ex() where scribus.redrawAll() is called(after writing text inside textframes).
Underlying sla doc. contains textframes and imageframes(+some lines). _insert_stylename_title() function inserts text to textframes and that may be essential for this problem. _remove_stylename_title() function removes these same written texts that are in form "<somestringname>"

When runnin my code, pointed_article(int) variable gets different values(for example 1...10) and thus rects are drawn and removed according that value. It is kind of preview which frame group is selected. (3,725 bytes) (6,811 bytes)
