> Would it be possible to tarball your .config/Gpredict directory so I can
give it a try?

Sure, here it is attached.  I also found out some more.  If I take ISS out
of the satellites list in "Configure", then the 100% CPU does NOT happen.
If ISS is reenabled, the 100% happens.

Please note: In the tarball config attached, ISS is NOT in the list of
satellites being tracked, so you have to add it back in on "Configure" to
reproduce the error.

I compiled version 1.3 from source and ran it under the debugger, and got
the attached stack trace when it was in the 100% condition.  I saw a
reference to the ISS data in the argument to one of the functions of the
stack trace, so that's why I tried taking ISS out of the display list.
Perhaps there is something funny about these particular ISS elements?

So then I wondered if it was perhaps due to the "decayed satellite" bug
reported in SourceForge tracker (ID: 3229639), which you had fixed with
commit 789.  So I checked out the SVN trunk (@ rev 826) and compiled it.
But the 100% happens in trunk@826 too, in the same place according to the
gdb stack dump, so the problem is not solved.

One other thing to note: with ISS out of the list, all is still not well.
After manually changing the time, if I then try to resume "real time" mode,
it jumps to Dec 13, 1901.  I also note in the stack trace that the first
argument to Calculate_User_PosVel() is "_time=_time=nan(0x8000000000000)".
I don't understand the code well enough to be sure, but that seems very
strange.

On the other issue: I tried running Gpredict under different windows
managers (plain gnome and twm) on the same netbook, and indeed the icons are
fine.  But the 100% when changing time manually problem still happened with
ISS enabled.  So the icon issue seems to be purely an issue specific to
"Unity", and the manual time control issue is unrelated to the window
manager.

In case it matters, I am using an HP netbook whose CPU is an Intel(R)
Atom(TM) CPU N455 @ 1.66GHz.

    Best regards.

Title:
  problems with time control: wrong icon, 100% on manual time adjustment

Status in “gpredict” package in Ubuntu:
  New

Bug description:
  Binary package hint: gpredict

  If I try to change the day or slide the slider in the time control, gpredict stops responding and uses 100% of CPU.
  Also (and this may be unrelated?) the  Time Controller  dialog shows the wrong icon for the "Play Backwards" button.
  Ubuntu 11.04 (natty).
  Seen with both 1.1-7 nd 1.3 (Specifically, gpredict 1.1-7 from ubuntu.com natty/universe and also with gpredict 1.3-ppa4+natty from http://ppa.launchpad.net/gpredict-team/ppa/ubuntu/ natty/main.)
