lupdate misses strings when called with absolute path

[rkohser]

Hi,

I am witnessing a really weird behaviour regarding the direct call of lupdate :
When I call

lupdate C:\project\source -ts result_fr.ts 

I get :

Updating 'result_fr.ts'...
    Found 56 source text(s) (14 new and 42 already existing)

but if I call it to scan the local directory, which is C:\project\source\ :

lupdate . -ts result_fr.ts 

I get :

Updating 'result_fr.ts'...
    Found 42 source text(s) (0 new and 42 already existing)
    Kept 14 obsolete entries

So it seems that the outcome of lupdate is dependant on the using of absolute/relative path. An interesting detail is that the 14 entries difference are only QT_TRANSLATE_NOOP calls. Does anybody have an idea of what's happening here ?

I am using Qt 5.6.0.

Thanks,

Roland
