Static plug-ins cause a crash if certain directories are missing

[Bogdan Marinov]

(Everything applies to the development version on Ubuntu, but, as far as I can remember, the same has happened on Windows.)

When Stellarium is run, some statically linked plug-ins try to access their subdirectory in ~/.stellarium/modules. If the /modules directory or the plug-in's subdirectory does not exist, Stellarium crashes with a segmentation fault at this point.

This has been confirmed by building and running for the Satellites plug-in, but the issue can occur with any plug-in that stores any kind of resource in ~/.stellarium/modules/PluginName.

Edited to add: Confirmed also with Oculars.

I fixed that for Satellites, and Tim said he fixed that for Oculars. I added a new method in StelFileMgr for handling that: StelFileMgr::makeSureDirExistsAndIsWritable()

Hi!

I am testing the current SVN (5771) on Windows XP/SP3 (minGW, QT4.6.0).

 Plugins and dirs:
-1) AngleMeasure: no dir; perfect
-2) CompassMarks: no dir; perfect
-3) Logbook: creates dir, but has some other problem,
             crashes on start when active.
-4) Oculars: creates dir, could be tested only once because of
             a frequent crash when object is clicked for identification.
    Great feature! Small Typo: "Magnifacation"-->"Magnification"!
-5) Satellites: seems perfect
-6) TelescopeControl: (without any further configuration,
    no telescope server etc.): loads some defaults, seems to work
    (at least does not disturb).

HTH, Georg.
