[Python-apps-team] Bug#682121: ocrfeeder: "too many open files" error after OCR of multipage document

[Michael Below]

Package: ocrfeeder
Version: 0.7.9-1
Severity: normal

Dear Maintainer,

today I tried to OCR a 39 page document I imported as PDF. After
viewing the results for the first two pages, the ocrfeed interface
was no longer updated -- I could choose other pages, but the
content shown was always for page 2. Saving the file, exporting it
etc. wouldn't work, the dialogs were not shown.

In the terminal I started ocrfeeder from, errors are displayed,
see below. The reason given is "Zu viele offene Dateien" i.e. "too
many open files".

Cheers

Michael
