This packages solves:
- #680946, severity important, avoiding different versions of libokularcore and
okular at the same time. The first 3 entries in the changelog are part of this
fix.
Three commits backported from upstream to solve:
- the extraction of the page bounding box, used by the trimming function;
- restore word detection in DVI documents;
- avoid a crash with broken fonts.

+ Avoid crash when the font is broken.
+
+ The call to FT_New_Face takes the address of the 'face' variable, whose type is a
+ typedef *something TF_Face;
+ The value of TF_Face (so a pointer to the properly filled font structure) s then
+ replaced inside the call of TF_New_Face; but when the latter function fails,
+ the value of 'face' is not reset and this leads to a crash in the distructor of
+ TeXFont_PFB.
+ So properly initialize TF_Face to 0, its address is valid, and the code works.

+ Fix word detection for DVI documents
+
+ This patch attempts to restore the functionalities broken by some changes
+ (maybe the text column selection code, it was broken also in 4.7).
+
+ Text search and text selection work (almost) properly again.
+
+ It uses a bit of heuristics to identify the end of a word and merge the
+ boxes which enclose each character of a word (so that
+ char_x.right==char_{x+1}.left).
+ It also tries to recognize if there is a newline ("after_space") after
+ that a space is found.

+Subject: [PATCH] Call Generator::signalPixmapRequestDone _after_ saving the
+ calculated bounding box
+
+Fixes a bug that causes the extraction of a wrong bounding box:
+
+If the request queue is not empty, signalPixmapRequestDone causes a new
+pixmap request to be started, thus overwriting mPixmapGenerationThread's
+mCalcBoundingBox before it is read by the if in the next line.
+
+Now signalPixmapRequestDone is called after the bounding box is saved,
+so that new requests are started only after all data from
+mPixmapGenerationThread have been saved.
