For me the icon is not missing, but it is replaced in the dock by what looks like perhaps a fallback: a cogwheel icon. I’m attaching a screenshot.

Hi Thomas, sure. Yes, the bug is still reproducible in Precise (gimp 2.6.12-1ubuntu1.2), which is what I’m using on my main desktop. But the good news is I can’t reproduce it in VMs running Raring or Saucy (both of which currently have gimp 2.8.4-1ubuntu1), so it looks like it’s been fixed in the 2.8.4 series at the very latest.

This looks slightly more straightforward than thebodzio’s method, so I’m picking this as answering my original query for ”easiest”. For some reason both Colorify and Colorize have been translated as ”Väritä” in my (Finnish) locale, so it would’ve been difficult to realize it’s actually two different functions. They’re not particularly easy to tell apart in English either…

Brilliant, this seems to work exactly as I wanted! And it seems to work for non-greyscale originals as well. Thank you!

I have an image I wish to colorize using a picked color. What is the handiest/easiest way to do this in GIMP?

I’ve tried my best by checking the palette for my picked color’s HSV, then using it as starting point to find corresponding HSL values for the Colorize window. But this seems absurdly difficult and imprecise. I don’t do much image processing, but I repeatedly come across this specific problem, so there must be a better way that I just don’t know about.

I now tried it in Natty, and while at it, in Oneiric as well. In both, GIMP still does exhibit the problem.

Sorry, forgot to mention that this happens on an up-to-date Lucid, but I was also able to reproduce it in Maverick. The backtrace was from Lucid.

Binary package hint: gimp

Steps to reproduce:
1. Start GIMP.
2. Create a new image.
3. Select Alignment Tool.
4. Click on image.
5. Close image.
6. Select ’Align right edge of target’ from tool options.

The problem seems to be that Alignment Tool options are activated (unghosted) at step 4, but don’t get disabled (ghosted) again at step 5.

Mitä kuvankäsittelyohjelmaa olet Windowsissa käyttänyt? Hyvällä tuurilla se toimii Linuxissa Winen avulla. Jos sinulla esimerkiksi on Photari-lisenssi, sen pitäisi enimmäkseen toimia Winellä. Natiiveja työkaluja en GIMPin lisäksi tiedä, mutten kyllä ole liiemmin sellaisiin perehtynytkään.

For me the ’dbusproxy != NULL’ problem came up with some of The GIMP’s filters. After I uninstalled Unity and all the packages it had pulled (probably from the PPA), the error went away. Hope this helps some of you too.
