I try to export a document: - Open "Export document" dialog - In "Export Steps", select only "Generated PDF(s)" - Press "Save as" and enter the filename I get the following log and a segmentation fault: [INFO ] [paperwork_gtk.mainwindow.exporter] Pipeline expanded: ['doc_to_pages'] [INFO ] [paperwork_gtk.mainwindow.exporter] Pipeline expanded: ['doc_to_pages', 'img_boxes'] [INFO ] [paperwork_gtk.mainwindow.exporter] Displaying pipeline: ['doc_to_pages', 'img_boxes'] [INFO ] [paperwork_gtk.mainwindow.exporter] Last pipe: Split page(s) into image(s) and text(s) ; Last output type: ExportDataType.IMG_BOXES [WARNING] [paperwork_gtk.mainwindow.exporter] Can't display export preview: unexpected pipe end: ExportDataType.IMG_BOXES [INFO ] [paperwork_gtk.mainwindow.window] Navigation: ['home', 'docview', 'exporter'] [INFO ] [paperwork_gtk.mainwindow.window] Showing exporter on right [INFO ] [paperwork_gtk.mainwindow.exporter] Rebuilding pipeline from UI [INFO ] [paperwork_gtk.mainwindow.exporter] Pipeline expanded: ['doc_to_pages'] [INFO ] [paperwork_gtk.mainwindow.exporter] Pipeline expanded: ['doc_to_pages', 'img_boxes'] [INFO ] [paperwork_gtk.mainwindow.exporter] Pipeline from UI: ['doc_to_pages', 'img_boxes', 'generated_pdf'] [INFO ] [paperwork_gtk.mainwindow.exporter] Displaying pipeline: ['doc_to_pages', 'img_boxes', 'generated_pdf'] [INFO ] [paperwork_gtk.mainwindow.exporter] Last pipe: Generated PDF(s) ; Last output type: ExportDataType.OUTPUT_URL_FILE /usr/lib/python3.8/site-packages/gi/overrides/GLib.py:497: Warning: g_object_notify: assertion 'G_IS_OBJECT (object)' failed super(MainLoop, self).run() /usr/lib/python3.8/site-packages/gi/overrides/GLib.py:497: Warning: g_object_set: assertion 'G_IS_OBJECT (object)' failed super(MainLoop, self).run() [INFO ] [paperwork_gtk.busy.mouse ] Mouse cursor --> busy [INFO ] [openpaperwork_gtk.widgets.progress] Task 'export' has started (0 already active) [INFO ] [paperwork_gtk.mainwindow.exporter] Preview: file:///tmp/paperwork-export-ccxzp0yz.pdf [INFO ] [paperwork_backend.cairo.poppler] Opening PDF file file:///tmp/paperwork-export-ccxzp0yz.pdf [INFO ] [paperwork_gtk.mainwindow.exporter] Preview size: 361548 ; Estimated final size: 2169288 [INFO ] [paperwork_gtk.busy.mouse ] Mouse cursor --> idle [INFO ] [openpaperwork_gtk.widgets.progress] Task 'export' has ended [INFO ] [openpaperwork_gtk.widgets.progress] Task 'export' has ended (0 remaining) [INFO ] [paperwork_gtk.mainwindow.exporter] Export settings defined.

Hey ulm, sorry I hoped to find time to dig more in this one but I see it has already been a while since bugreport :/ That it shows "Generated PDF(s)" confirms it is a scanned document (so not just a potentially non-standard imported PDF). I guess checking the stored image file could show some clues, in the storage directory, each document is a directory with timestamp like: 20200303_2326_01: labels paper.1.jpg paper.1.thumb.jpg paper.1.words Redoing the OCR may help, though I do not think it is used in the end-result PDF I see https://gitlab.gnome.org/World/OpenPaperwork/paperwork/-/issues/942 upstream which looks similar
In fact, I couldn't reproduce the problem with any other document, and for the document in question exporting succeeded with different export options. (Curiously, I hit this problem just after updating to version 2*, so I suspected that it was related to the new version.) So, feel free to close this bug.
Cleaning old bugs, I forgot to close this one
Reopening. I can reproduce the problem with at least 3 other documents.

With the Flatpak version from https://builder.openpaper.work/paperwork_master.flatpakref exporting to PDF works fine.
