[Bug 1890013] [NEW] ocrfeeder PDF import systematically fails

[Launchpad Bug Tracker]

You have been subscribed to a public bug by William Wilson (jawn-smith):

[Impact]
 When attempting to import PDF files, a scenario frequently
 occurs in which the import fails with no error message.
 This happens because ocrfeeder does not wait for the call
 to ghostscript to finish running before attempting to
 read its output.

[Test Plan]
 * Run ocrfeeder
 * Click File -> Import PDF
 * Choose a PDF file with many pages, as this will
   be more likely to trigger the bug
 * Observe that none of the PDF pages appear in ocrfeeder
   and it states "No images added" in the lower left corner
 * Install ocrfeeder from -proposed
 * Attempt to import the PDF file again, and observe that
   all of the pages appear in ocrfeeder

[Regression Potential]
 If the ghostscript call hangs indefinitely for any
 reason, the ocrfeeder application will also be hung.

[Original Description]
Using the File menu of ocrfeeder :

-  Adding a JPG image systematically succeeds,

-  Importing a PDF systematically fails (without any error message).

Please fix the handling of PDF by ocrfeeder.
