When kile open a document it parse it to create the structure. The parsing was fast with the lenny (1:2.0.1-1) package but is now to slow. I would like very much to have the speed of the previous version.
This problem occur only when the "Structure" on the side bar is shown and a lot of section. In this case the structure of the tex file can be analysed several times (more than 4 with my file).
