Version: (using Devel) OS: Linux Installed from: Compiled sources When going over a .mp4 file (in my case large file ca. 1GB ) dolphin freezes for about 20 seconds if you go over it for the first time in. Seems to use a lot of memory while doing this: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 317 gunni 20 0 431m 31m 7176 S 27 1.6 43:43.82 mythfrontend.re 5953 root 20 0 574m 25m 5480 S 12 1.3 113:08.92 Xorg 18038 gunni 20 0 1434m 936m 21m D 12 46.6 0:10.54 dolphin 6390 gunni 20 0 309m 13m 10m S 6 0.7 0:54.35 yakuake 31250 gunni 20 0 527m 134m 12m S 4 6.7 28:34.36 firefox 46.6% memory, it seems like dolphin reads the whole file. If you go over it a second time its ok, until you restart dolphin. KDE 4.2beta 2 from kubuntu packages. Preview not enabled, symbol view.
I suppose this is related to Strigi file analyzer. What strigi version do you have ? (you can do "strigidaemon --version" in a Konsole to get the version) Thanks
gunni@desktop:/media/ext3/movies$ strigidaemon --version strigidaemon 0.5.11
I can confirm that this is an issue for me too. Dolphin freezes for a good number of seconds. I am running kde-4.1.3-1 on Fedora 10.
I've added Jos (= strigi maintainer) to CC, I'm not sure whether this is already fixed with a recent strigi version.
Fixed here. Updated to 4.1.4.
Just to make sure: what's the strigi version now?
Same issue with kde 4.2 final. In Dolphin, if I remove the Informations panel (F11) I can hover mp4 files withou any problem. Otherwise, hard drive heavy activity that blocks Dolphin. Neither Nepomuk or Strigi are active. So it looks like a Dolphin only bug.

As far as I've seen one problem might be that the implementation currently seems to ignore the KFileMetaInfo::Fastest hint, but I trust in Jos that he knows better than me about a sufficient implementation ;-)
I experience the same problem too. I recently updated to 4.2. Running Fedora 10. I mentioned in an earlier post that version 4.1.4 the problem seemed to go away.
*** Bug 184363 has been marked as a duplicate of this bug. ***
Running Kubuntu 8.10, KDE 4.2, Dolphin 1.2 and finally strigidaemon 0.6.3. Neither Nepomuk or Strigi are active. After pointing on MP4 file I am registering heavy usage of HDD for couple of seconds. Than Dolphin crashed and caused the signal 11(sigsegv). Backtrace is not available because of some warning (invalid backtrace or something like that..)
Happening on 2 systems for me: ----------------------- OpenSuSE 11.1 KDE 4.2.1 Dolphin 1.2.1 strigidaemon 0.6.4 ----------and---------- OpenSuSE 11.1 KDE 4.1.3 Dolphin 1.1 strigidaemon 0.5.11 ----------------------- Same problem... Very annoying when mousing over all my 1.5GB DVD rips and all my RAM gets eaten up - makes Dolphin very un-usable. I also noticed a slight pause when I moused over a MOV file. Unfortunately the biggest I have is <100M, so I can't do a conclusive test on that type - perhaps someone else has a large MOV file they can mouseover? Large AVIs have no problem at all. Just as wazyk stated, this only seems to happen when the information panel is open - if I close it there is no issue. Doesn't Dolphin use taglib for it's information panel? If so, could taglib be at fault? Finally, where is the MP4 file is meta-data stored? Presumably the pause is while Dolphin waits for it to be retrieved, so if the meta-data is somewhere weird in the file then the delay is it looking for the data. A few possible work-arounds; A: Background the process that retrieves meta-data B: Cache all meta-data, (longer than session) or at least for filesize > X C: Don't retrieve meta-data at all for filesize > X
> Doesn't Dolphin use taglib for it's > information panel? If so, could taglib be at fault? Dolphin uses KFileMetaInfo from kdelibs, which uses Strigi internally. In Dolphin for KDE 4.3 the Information Panel does not use KFileMetaInfo anymore, but uses Nepomuk instead -> no blocking occurs in this case anymore and additional meta information can be received very easy...
@Peter: Should this be closed now ? Thanks
Same issue with kde 4.3 beta and the "tooltips show previews" enabled. No problem with the Informations panel.
Dolphin still freezes when going over a mp4 file with enabled tooltips. No problem if tooltips are disabled. I have kde 4.3 beta (suse 11.1), please change the status of this bug.
@Salvatore and Luca: The issue with the tooltips is a slightly different one. I've submitted a new bug 195878 for this specific use case and would like to keep this bug closed. Huge problem: because of the string freeze I fear bug 195878 cannot be solved for KDE 4.3 - hm, maybe I find a workaround to solve this for KDE 4.3 without adding strings...
