There are three bugs in pisensors:
  1. (non-crash) The background color is light gray instead of what the theme color is.
  2. pisensors doesn't start from appmgr or perhaps starts but crashes immediately.
  3. pisensors crashes if you run it manually and then click on a cell entry that has nothing in it. Here is the backtrace for this one.
    (gdb) bt
    #0  strlen () at ../sysdeps/arm/armv6t2/strlen.S:85
    #1  0x76552798 in __GI___strdup (s=0x0) at strdup.c:41
    #2  0x000152f8 in dbModifyEntry (entry=0x0, delete=0, state=1) at db.c:326
    #3  0x000129ec in toggleState (entry=0x0) at pisensors.c:287
    #4  0x00012b64 in button_press (widget=0x58950, event=0x88680, user_data=0x4)

    #5  0x76d32b3c in _gtk_marshal_BOOLEAN__BOXED () from /usr/lib/
    #6  0x76828cf8 in g_closure_invoke () from /usr/lib/
    #7  0x7683960c in ?? () from /usr/lib/
    Backtrace stopped: previous frame identical to this frame (corrupt stack?)

The last one is probably just not checking that the click doesn't map to a dbEntry.
The second one requires running pisensors -v3 -l/tmp/pisensors.log from it's launcher XML config.
The first one is just a cairo thing - check what the media player launcher does or maybe just make it black.

Clicking on an empty cell is fixed. This is only for mouse clicks, which you have if you run the app manually and display it on your desktop (sans touchscreen).

Touchscreen stuff is not yet implemented for pisensors.

Fixed the app to read the system default gtkrc on startup. That fixes the background color problem.

Fixed the icons to be readable by the user "nobody", which is the unprivileged user that runs the app via appmgr. That fixed the other crash problem.

Tested on hardware. Changes committed and pushed.

Closing issue.
