TYPO3 Core

If you have entered some values in the 'All Configuration' page of the Install Tool, then you try to edit and save 'Basic Configuration' page, some of the values are being overwritten.

For example, in 'All Configuration' page, I set the following options:

[GFX][im_combine_filename]=composite
[BE][disable_exec_function]= 1
[GFX][im_version_5]= im6
[GFX][gdlib_png]=1

However, under the 'Basic configuration' page, these settings are reported like this:

[GFX][im_combine_filename]=combine
current value is combine

[BE][disable_exec_function]= 0
current value is 1

[GFX][im_version_5]= im5
current value is im6

[GFX][gdlib_png]=0
current value is 0

Therefore, if I need to change a setting like database name etc in the basic config page, after updating localconf.php, the im_version_5 setting will revert from the current value of im6 to im5; thus the admin has to reset im6 via the all config page. It also applies to disable_exec_function variable, and maybe others too, but these I can confirm.
