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"?

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.
