[ansel] imageCreateFromString Empty string or invalid image

[vuser1]

Hello ansel users!

 

Yesterday I installed horde-webmail-1.2.3 and ansel-h3-1.0. Image gallery with preview thumbnails works fine, but website cannot render the image when I click on it. In /tmp/horde.log:

 

Jul 01 13:22:21 HORDE [error] [ansel] imageCreateFromString: imagecreatefromstring() [<a href='function.imagecreatefromstring'>function.imagecreatefromstring</a>]: Empty string or invalid image [pid 20055 on line 175 of "/usr/share/horde/ansel/lib/ Views/Image.php"]

Jul 01 13:22:22 HORDE [emergency] [ansel] imagejpeg: imagejpeg(): supplied argument is not a valid Image resource [pid 20055 on line 44 of "/usr/share/horde/ansel/img/screen.php"]

At first I tried to install imagick (pecl install imagick), but later I disabled it in php.ini. 

The line producing an error:

173:        $geometry = $this->resource->getDimensions('screen');

174:        if (is_a($geometry, 'PEAR_Error')) {

175:            Horde::logMessage($geometry->getMessage(), __FILE__, __LINE__, PEAR_LOG_ERR);

 

I am in stuck, why thumbnails works, but image view – don’t? What should I try/check?
