Description Olivier Kes 2011-07-22 19:03:33 UTC 
Version:           2.0.0 (using KDE 4.6.0) 
OS:                Linux

When loading a large GPX file in GPS Correlator, the panel remains disabled.
With a small file, it is disabled while loading, and then enabled again.

If I renice digikam process to the lowest priority before loading the file, then it works.

Reproducible: Always

Steps to Reproduce:
Load a large GPX file

Actual Results:  
The panel is disabled (grayed)

Expected Results:  
The pannel should be enabled

OS: Linux (i686) release 2.6.37.6-0.5-default
Compiler: gcc

The disabled correlator

Though the file is properly loaded, all the commands for correlation are disabled. I can only close the window and open it again.

Sounds like some problem with signals from the threaded loading, just guessing.

How large in MB is "large"?
Comment 3 Olivier Kes 2011-07-23 14:59:13 UTC 
Not that large, actually. With my Acer Aspire 1652 Wlmi, Intel Pentium M 740 (1,7 GHz), I could load small tracks of ~100ko, but not much more.

When lowering the priority of digikam, I was able to load files over 10Mo.

Hi Olivier,

I can reproduce your problem when booting my quadcore with the 'NOSMP' kernel option, making it effectively a one core system and will look into it.

Properly detect when the QFutureWatcher reports that loading of the GPX files has been completed.
