Thanks Ralf and Bernhard for your answers.
Sorry, my message wasn't clear, I'm trying to use the dissolve tool from
the processing toolbox. Other dissolve tools won't do, since I use this
tool for an extension I created (dissolve with stats), which calls the
qgis:dissolve algorithm from the processing toolbox.
I'm using QGIS 2.8.3 Wien. Does it mean I'm not using your patch Bernhard ?
Thanks again,
Julie.

Hi,
I worked on the dissolve tool recently , and the work got commited a
couple days ago [1]
So, if you are using current master, you must set the dissolve field
for the layer. If you are using a stable version of QGIS (e.g. 2.10)
you must untick the checkbox "Dissolve all (do not use field)". I
recommend to use my patch because it is a lot faster than the old
algorithm.

Hi all,
I tried using the dissolve tool from the QGIS geoprocessing tools and
all features get dissolved together, resulting in only one feature,
regardless of the dissolve field. I tried with several datasets. Do you
have the same problem or is it only me ? I've used this tool in the
past, and it worked ok.
Thanks for your help !
Julie.
