** Description changed:

+ [SRU] The patch attached to comment #4 backports the following changes from 
2.1.5-10-17 in Saucy:
+ - patches/add-required-libs.patch: Link with -lXm before -lXt. (LP: #1006988)
+ - patches/buildsystem.patch: Use xdg-open as PDF viewer. (LP: #1208162)
+ - patch/configurability.patch: Fix opening About page in revo. (Upstream 
revision 46200)
+ 
+ [IMPACT]
+ Attempting to run any of the programs listed below fails with the following 
error:
+ 
+ Warning: XmManager ClassInitialize: XmeTraitSet failed
+ Error: attempt to add non-widget child "DropSiteManager" to parent "ivview" 
which supports only widgets
+ 
+ In package inventor-clients:
+ /usr/bin/ivview
+ /usr/bin/SceneViewer
+ 
+ In package inventor-demo:
+ /usr/lib/inventor/drop
+ /usr/lib/inventor/gview.RUNME
+ /usr/lib/inventor/maze
+ /usr/lib/inventor/noodle.RUNME
+ /usr/lib/inventor/qmorf.RUNME
+ /usr/lib/inventor/revo
+ /usr/lib/inventor/SceneViewer.RUNME
+ /usr/lib/inventor/textomatic
+ 
+ Additionally, all of the above programs are hard-coded to use xpdf for
+ displaying their help pages (LP: #1208162). Xpdf would not be installed
+ on a typical desktop as libinvenotr's recommends in Ubuntu were on xpdf
+ | pdf-viewer, which would be satisfied by the desktop's default PDF
+ viewer even though it would never be used.  If xpdf is installed, it is
+ almost guaranteed to segfault while opening any document (LP: #943195).
+ 
+ [Test Case]
+ Install inventor-clients and inventor-demo:
+ $ sudo apt-get install inventor-clients inventor-demo
+ 
+ Run any of the programs listed above, for example:
+ $ /usr/lib/inventor/qmorf.RUNME
+ 
+ Verify that the program is able to start.
+ Click on the About button, or from the menu; File / About, and verify that 
the About or help page is opened.
+
