Description e3k 2010-11-25 16:24:09 UTC

Version:           unspecified (using KDE 4.4.5) 
OS:                Linux

dolphin freezes when cutting many files (500-1000) in icon view. did try with empty files, images and mp3 files. its the same.

when cutting a few files with sum of 5gb its not an issue.

pressing ctrl+c is not an issue.

Reproducible: Always

Steps to Reproduce:
go to a folder with more than 1000 files.
switch to icon view
ctrl+a
ctrl+x


Actual Results:  
the dolphin window freezes for seconds or minutes depending on the amount of selected files. if too many files are selected you can think its a crash.

Expected Results:  
no freeze

Thanks for the report. I cannot reproduce the issue locally here and my current guess is that it might be a graphics driver issue, because the "grey icon effect" is applied to each cut icon. Does the situation change if you start Dolphin like this:
dolphin -graphicssystem raster
?

no i have still the same issue with dolphin -graphicssystem raster

> the "grey icon effect" is applied to each cut icon

The effect should only be applied on visible items, otherwise I would consider this a bug.

Regarding the delay, could Klipper be an issue? Try quitting Klipper and check if you can reproduce.

did quit klipper. still an issue.

Comment 5 e3k 2010-11-26 09:59:10 UTC

did read this in /dolphin/src/dolphinview.cpp:


void DolphinView::cutSelectedItems()
{
    QMimeData* mimeData = selectionMimeData();
    KonqMimeData::addIsCutSelection(mimeData, true);
    QApplication::clipboard()->setMimeData(mimeData);
}

void DolphinView::copySelectedItems()
{
    QMimeData* mimeData = selectionMimeData();
    QApplication::clipboard()->setMimeData(mimeData);
}


the difference between copy and paste was the KonqMimeData::addIsCutSelection(mimeData, true); line.

so i tried the same in Konqueror and quess what happened.

same issue in kde-base/konqueror-4.4.5

after upgrading to 4.5.4 the issue is gone.
